It works on real hardware, but depends on the size too. If 800 x 600 or better
(1024 x 1024, 1024 x 768) I can change the background, but less than that it
does not stick. Oh, it does not modify the registry, so after a reboot, I get
the same original background.

With winfile.exe;

(objects/gdiobj.c:803) Attempted to lock object 0x0 that is deleted!
(objects/bitmaps.c:71) Invalid source dc handle (0x00000000) passed to NtGdiBitB
lt

Palbitblt;

(objects/gdiobj.c:603) Attempted to free global gdi handle 0x605025f, caller nee
ds to get ownership first!!!

FYI, I can install OOo_114_Win32 with some gui problems but it did trash my
registry entries and made Foo.lnk to everything. So I reinstalled registries.

OpenOffice 1.1.4 and WinQuake;

GDI32: CreateDIBPatternBrush is unimplemented, please try again later.

OpenOffice 1.1.4 after exit, it's still there;

(objects/gdiobj.c:845) Attempted to lock foreign handle: 0x80402f0, Owner: 0x214
  locked: 0x0 Caller: 0x100, stockobj: 0x0

Taskmgr; Hay it work now, Performance page looks like it needs some fixing up
(win32k.sys, maybe?)! After exit Taskmger get this,

(ntuser/message.c:1135) Attempted to post message to window 0x19c that is being
destroyed!

I used pskill to kill it off, or you can use a new taskmgr window to kill the
one you exit from.



Thanks,
James
