Hi Austin,

I made a regression test.

In wine-git folder, i launched these command :
1-
git bisect start
git bisect good wine-1.3.18
git bisect bad wine-1.3.19

The first message after the last command is this :
[a42bf0134c74cd1971750812b0df18b6e8ffacdf] msvcrt: ungetc must create a buffer,
even if _IONBF has been set with setvbuf.

Result = Game crash after to recompile

2- 
I launch "git bisect bad" because the bug is still present. Now, the message in
the console is :
Bisecting: 86 revisions left to test after this (roughly 7 steps)
[513e5c98a76c89b16639203ca8823680622e2795] user32: Add support for loading
animated cursors/icons from resources.

Result = Game doesn't crash after to recompile. Graphic bug like with wine
1.3.18 and < (shadow square and film grain)

3-
I launch "git bisect good" because the bug was not present. The message in the
console is :
Bisecting: 43 revisions left to test after this (roughly 6 steps)

ID3DXBaseEffect::GetParameterElement().

Result = Game doesn't crash after to recompile. Graphic bug like with wine
1.3.18 and < (shadow square and film grain)

[c852200b03ab3874ffdd4c02da947163c9f3990a] wined3d: Get rid of
IWineD3DSurface::GetType().

Result = Game doesn't crash after to recompile. Graphic bug like with wine
1.3.18 and < (shadow square and film grain).
But the mouse is incontrolable.
