Hello,

the "hang" is a combination of wine bug and sloppy programming of game guard
devs.

The hang occurs in gameguard.des process while trying to load a splash screen.
Due to a bug in wine oleaut32 api function, a hang occurs because specific
assumptions are not met/some code paths are not executed.

--- snip ---

oleaut32.OleLoadPicturePath() returns with 0x800401F0 error -> "CoInitialize
has not been called" - which is of course true.
Due to that error, some (threaded) code is incorrectly skipped.

I wrote a small test client under windows xp to verify.
It seems OleLoadPicturePath implicitly initializes OLE in its apartment (= no
explicit CoInitialize() needed).
So clearly a wine bug.

You can either fix this by using native oleaut32.dll override or by explicitly
calling CoInitialize() and CoUninitialize() before any CoCreateInstance() calls
in that api function.

Regards
