I've installed WA again, and now all menu's are messed up. All colors have been changed, but in the original files and ingame all seems normal. I think there is an problem with DirectX. I've the newest WA patches.

My system is Windows XP Pro, DirectX9.0c, ATI Radeon 9550.

EDIT: WWP does work correctly, without those problems.

Any programs running backround which could cause the colors to invert or something like that ?

No, nothing. Just the Windows XP kernel, DirectX drivers and WA.

RANDOM APOSTROPHE ALERT! >>>> "menu's" <<<<


I always get inverted colours when I minimise in-game. This is always fixed by minimising and restoring again. Have you tried that? (Minimise from the main menu by clicking right at the bottom of the screen...)

Have you tried that?
Now have I tried that, but it didn't work.

but in the original files [...] all seems normal.

Does that mean that you kept your old working install of W:A?

You could try to compare the two directories, and then try to find the difference which is causing the problem.

No. I opened the images. (.\Graphics) All normal.
