Hi all, I've a strange problem affecting my Ubuntu Gutsy box, and I hope someone with more experience than me can explain why I'm having such a behaviour...

Simply, when I try to play Warcraft 3 installed following all the tips in the AppDB with my pc, I receive an error related to memory read/write... but when I try to launch WC3 with sudo wine Warcraft3.exe the game start and I can reach the menu, where everything runs at like 10 fps... is there anyway for me to resolve the memory error without having to use sudo?
For example, Diablo 2 runs fine (in direct2d, opengl mode is all blocky, but who cares), like may other apps I tried, so what's the problem with Warcraft 3?
