what is this show common tasks.... Is it part of adobe or windows and does it apply also to winxp and if so how do you get there?

Most certainly NOT . It is most rude for adobe to come up with this and suggest people upgrade or use it when it made it MUCH WORSE and way to slow if it works at all. I wish there was a way to uninstall it and go back to a previous version but guess not. If anyone has discovered a way to uninstall the latest upgrade and go back to previous version PLEASE  POST.

Thanks but Actually I had already done that and also unchecked the enable enhanced security. Perhaps it did improve it somewhat but still is slower and more problem to use than prior version(s).Besides being too slow it seems usually to even open a 2nd or higher file when I push enter it does nothing and have to keep on pushing enter till it finally does it or messes up things so much I need to reboot or something - same thing with rt. clicking and going to open with adobe it ignores my command more often than not esp. when have other applications open whereas prior versions did not have this problem.

I think different people are experiencing different problems here on this thread but I can at least say from my point of view the issue remains with Pro 10.1.0 on XP SP3 opening the 1st PDF is fine but opening subsequent PDFs is almost always, but not always, preceded with an unusually long delay before they open.  I did some brief testing with Pro 10.1.0 on Win7 x64 SP1 and did not reproduce the issue, but at least one other person on this thread says they have had it happen on Win7.

I have tried these things and none of them helped:

- Turned protected mode on. (It was off by default). Turned it back off. No difference either way

- Turned enhanced security off. No difference

(both of these are under edit > preferences > security (enhanced) )

- Uninstalled Adobe Reader. I had Reader 9.4.5 installed as well as Pro 10.1. After uninstalling that, no difference in this behavior.

- Temporarily disabled Symantec Endpoint Protection 11.0.6300.803. No difference in this behavior. Note there is a known bug with Adobe Reader 10 and Symantec Endpoint Protection versions lower than 11.0.6200 - Reader 10 will not run in Protected Mode.

What does help is to roll back to Acrobat Pro 10.0.0 When I do that (which so far I can only get to happen by uninstalling and reinstalling) I have yet to get the slowness to occur with 10.0.0

Please pleese pleeeze can someone tell me how to remove Acrobat reader X and replace it with

one that works Acrobat 9.

I'm tired of trying all of the helpful suggestions above, none of which have worked, but thanks anyway.

McP.

Acrobat reader, thanks. Made the mistake of saying Yes when Adobe said there is a new version of Acrobat reader

. Hmmm.

Most people make that mistake.

It all goes back to the saying "if it aint broke...don't fix it!"

I'm not sure if this has anything to do with it but....   having just checked my 'reliability monitor' (via control panel) - there is an warning mark right next to Acrobat X Pro with the message 'Unsuccessfil application reconfiguration'. I haven't asked Acrobat to do anything today so what ever the error is, it's done it off it's own back. (As you'll see from previous notes, i too am having issue's since the update. Using Windows 7 Ultimate SP1)

My Acrobat recently got updated to version 10.1.1 and now it opens pdf files without any delay. I would suggest all of you facing this problem to update your Acrobat to latest version (10.1.1) as soon as possible.

Regarding the ridiculously slow opening of PDF's in IE8 web browser (I know not OP's problem), it is still ridiculously slow with Acrobat 10.1.1 and Reader 10.1.1 installed.

If I uninstall Acrobat X and leave Reader (10.1.1) installed they open damn near instantaneously in IE.

Install Acrobat 10.1.0, PDF's can take up to 60 seconds before viewable.

Update to Acrobat 10.1.1, PDF's can take up to 60 seconds before viewable

Turn off all the addins in browser, no change.

Any definite fixes for this anyone .. please? Preferably one I can recommend to external clients as well as they are having the same issue viewing the PDF's off our website.

That's in the browser lenahanson?

I just downgraded Acrobat to 10.0.0 and it's instantaneous again (Reader 10.1.1). Can't really tell customers to do that though .. damn.

The problem for me also went away when I updated to v10.1.1. (for WinXP)

The problem is mostly about having thumbnail views applied to your folders and the setting (in XP) "show common operations in the same folder".

If I turned that feature off, the problem went away (with the previous version).

I can still sense some delay in opening of PDFs, with the new version, but nothing like before.

Yeah, I use Chrome myself and the builtin PDF viewer is instantaneous. Can't really tell our clients who work at hospitals etc to change their browser though (IT won't let them), or to turn off "Display in browser" in their Acrobat settings, or to right-click and save as.. to speed things up.

Would be better if Adobe could just tell us where the problem lies or even better .. fix it.

Exact same setup in out org nzorn and exact same results.

Is Adobe going to fix this? I can't log a support case as don't have support details.

Hey nzorn, maybe you can verify this for me:

When I RDP into computer it works instantly (ie. normally). If I'm sitting in front of it or VNC/DameWared it is ridiculously slow (can be over a minute). This made me think it is something to do with the video driver (god knows why, Adobe you're a champ. /sarc).

Updated driver to latest version (ATI Radeon HD2400XT), no luck. Used the onboard video (Intel Q45/Q43 Express Chipset), no luck.

DISABLED the driver (so computer reverts to stock VGA), PDF's load instantly! Enable the driver, back to square one.

ATI and Intel can't be blamed because 1. It works pre 10.1 and 2. They are totally different companies.

Please somebody from Adobe read this and fix this! We run breast cancer trials as a subsidiary for a University (VLK license) but don't have support logon details where we're situated. Surely it's more than just us and nzorn with this issue!

I solved the issue for myself by disabling the "preflight" plugins by moving the 3 files from the acrobat plugins folder (Preflight.api, Preflight.deu, Preflight.fra).  More details about this can be found here:  http://forums.adobe.com/message/3791427#3791427.

Not saying this is a solution, as I believe this to be a bug, but at least files are opening at the same speed as they were before this update. 

*Also, after testing (once files were moved), I put them back in the folder, and even restarted, and it's still fast.

Here's our environment:

• Windows 7, x86 SP1
• Intel Core 2 Duo CPU, 3GB RAM
• We render PDFs from our networked file servers. At times, from IE8, but main issues are from our file servers
• Issue is most noticeable with first/initial launch of PDFs. Subsequent launches are quicker.
• We typically double-click from Windows Explorer, open UNC links, or open attachments from Outlook 2003.
• We have Adobe Acrobat X Pro, 10.1.1. With 10.0.0, we had no issues with networked PDF files
• Users typically multi-select a number of PDFs, then open from Windows Explorer - but that operation is very slow now.
• We have a mixed Adobe Reader X/Acrobat X installation
• By Default, Enable Enhanced Security and Protected View is enabled (Acrobat)
• Our workstations and servers are on the same Trusted Zones.

Thanks for your help.
