I think you need to ask about Photoshop in that forum http://forums.adobe.com/community/photoshop
In general, go into your options (not sure where, set mine a long time ago) and tell Adobe Updater NOT to run automatically
You will, of course, need to check for updates yourself
All Adobe updates start here and select product http://www.adobe.com/downloads/updates/
I think you may be talking about Photoshop.com, Adobe's free internet portal for displaying photos and video, backing up files, getting free tutorials and receiving new templates and themes for your programs. (In my books, I detail all of these services and the great reason for logging on to this service -- which should not be dragging on your internet connection unless your program is complete idle.)
If this is the case, just log off and it will no longer exchange data with it. You can log off from within the program by just clicking on the link that says "Hi [Your name]" at the top of the interface.
Thanks for the reply guys but looks like I may have jumped the gun somewhat. Prior to the original post I had turned off Web Sharing but the DL kept operating and that is when I decided to ask for help. When I fired up the prgm after writing I noticed there was no internet activity. Maybe a new cession was needed before the changed setting took affect. Anyway, looks like issue is resolved.
Again, thinks for the replies.
Thank you for reporting back. Though I do not know Photoshop.com, many services will continue to run, even when Preferences are changed. That change will not appear until a reboot. I hope that is your issue here.
