The screens are blank, the entire window is mostly white. If I press in the top right corner of the window to minimise the window and restore it the window redraws itself properly but if I open a display the display opens all blank. continuiously minimise and restoring windows will redraw the screens but you cannot develop like this. Running windows XP SP3
I found this on the knowelegebase but it did not help.
I am using my laptop with a second monitor. I will try it tomorrow on the Laptop undocked. Going home now. Thanks a lot.
Desktop Heap Allocation in the Registry
The size of each desktop heap allocation is controlled by the following registry value:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Session Manager\SubSystems\Windows
Default Registry Value
The default data for this registry value will look something like the following (all on one line):
%SystemRoot%\system32\csrss.exe
ObjectDirectory=\WindowsSharedSection=1024,3072,512
Windows=On SubSystemType=WindowsServerDll=basesrv,1 ServerDll=winsrv:UserServerDllInitialization,3ServerDll=winsrv:ConServerDllInitialization,2 ProfileControl=OffMaxRequestThreads=16
The solution is to modify the SharedSection value (highlighted in the registry key above) by increasing its third value (highlighted in blue) from 512 to 1024. The modification has been already included in the attached registry key. After the registry is applied, a reboot is mandatory.
Thanks
