Cannot open new windows/applications!! RRS feed

  • Question


    Hi everybody.

    I am having some trouble with my new Sony Vaio in Windows Vista Buisness. I have installed all the required updates and there are no more available.
    When i have had my computer turned on for about 10-15 minutes and have about 5 windows/applications open, it won't let me open any more and i can't even access the context menu form anywhere. I then close a couple of windows and then i can open another one, but it keeps doing it and at the end i only have one window open and can't open more. So after 30 minuttes use i have to restart to get it to reset and let me open some windows and access the context menu.

    Please help, this is so annoying. I have tried editing the desktop heap size to 4096, but that doesn't help at all.

    Let me know,
    thanks alot in advance,

    Does this system have the Service Pack 1 installed?


    If not, I would recommend installing the SP1 update. This will increase the default Heap Size to 12MB.


    Don't forget the Caveat when changing the Desktop Heap Size:

    "Please do not modify these values on a whim. Changing the second or third value too high can put you in a no-boot situation due to the kernel not being able to allocate memory properly to even get Session 0 set up" 


    See the following articles for reference.
