OK, so while several of my apps do work under Wine, some of them do exhibit problems, like in Photoshop CS5 which throws out an exception: Code: wine: Unhandled page fault on write access to 0x00000014 at address 0x6315de8 (thread 0031), starting debugger... Unhandled exception: page fault on write access to 0x00000014 in 32-bit code (0x06315de8).

Do I need a new prefix for it, or am I missing a library file? ATMLIB's already present in my prefix. Another thing was that with Mafia II lacking shadow maps. I know some of them testers managed to make it work, but not in my case when I'm running the game in 1.3.27.
