    @shdskj__gfd,

    As this topic began in 2010 re: CS5, you might want to look at newer discussions re: CS6.

    Nancy O this doesn't solve the problem either yet Adobe Dw CS6 still spikes my one out of four core to 80 to 100% .

    I have done all prefrence deleting ,cache cleaning, registry editing which are posted in this forum but all these have no impact to Dreamwever.

     

    I don't know why Adobe just release a patch and fix this issue because people buy these products so the "Company" should have a responsibility to fix these issues.

    I solved that issue for Dreamweaver CS5!

     

    Somehow the main window message handler of the consumes very much CPU power. In detail the mfc90u.dll!#6019 part that uses USER32.PeekMessageW.

    Here is the patch:

    (Original Post:

    )

    I guess things in DW CS6 are still the same.

    Well to get this patch applied the first issue will be to find the right mfc90u.dll inside the windows side-by-side mess

    c:\Windows\winsxs\

     

    Next issue might be to fight for ya right to write.

    • mfc90u.dll might be in use by DW or other applications(processhacker may help ya here again to find open handles to mfc90u and close them; or kill the process)

     

    • Maybe you've not have enough access rights to write to files that are in the Windows\ folder. As admin you might need to take over ownership before you can garnt you full access to the folder(and files) mfc90u.dll is in. Right click on the folder and choose propertiers/security to set that kind of things.

     

    Important: Please give some feedback if you got this also working for CS6.

    ... and the path to mfc90u.dll for CS6 like for example:

    c:\WINDOWS\WinSxS\x86_Microsoft.VC90.MFC_1fc8b3b9a1e18e3b_9.0.30729.41 37_x-ww_a57b1f13\mfc90u.dll

    The 100% CPU issue has been fixed in Dreamweaver CS6 update 12.1 for creative cloud subscribers and 12.0.3 for non-subscribers.

    Sorry, but this is not fixed in my experience. I have version 12.0.3.5861 (fully updated as of today), and Dreamweaver is taking 100% CPU - not just at startup, but much of the time. I am having to fully force quit and restart Dreamweaver and my Mac many times each week (often multiple times/day).

    I'll look for answers in other threads.

    Thanks.
