Share Memory Issue

[James Tabor]

Hi all,
Fixing GetDeviceCaps exposed a thread process shared memory issue with
WinLogon and Gimp.... Gimp bug, been around and the crash does not
make sense until you see where the fault was located. Where? In client
thread share memory. So, we need help and soon I will revert the hack
in GetDeviceCaps. Maybe we are not passing everything to User32 that
is needed.

Thanks,
James

Hi!
The best clue to the problem I can find is this:

Hi!
Someone tell me why this looks wrong:

(ntoskrnl\vdm\vdmmain.c:25) VME detected but not yet supported
(subsystems\win32\win32k\ntuser\misc.c:59) Language ID = 409
fixme:(dll\win32\shell32\iconcache.c:413) Failed to load
IDI_SHELL_DOCUMENT icon!
(subsystems\win32\win32k\ntuser\hook.c:1056) Not implemented: HookId

Thanks,

Reminds me of something trying to create icons before we had a window
station....

I guess we need CsrClientConnectToServer in user32's dllmain:
