I don't know if these effect anyone else but with the "native" version of Warcraft 3 I get all sorts of problems. So I got fed up and got the trail of crossover games, had a little trouble with getting it to install (had to download the windows version off the website as the disk will not let you choose). But after this little hick up I was ready to go then remembered I wanted to have windows which mean you need to do the following. Run Command > (find war3.exe should be easy to find) > add -window -opengl else artifacts will appear when you change the screen. I did all this and found that the game crashes when you login in to battle.net.... So question time has anyone got it working on crossover? Also has anyone figured out how to access the drive_c to add more maps etc? *edit 1* Picture of Crossover Crash Error *edit 2* Seems you can stop the game crashing so much by removing the movies folder located at. Also the Map folder is also in this place. I've also found out a way to modify WINE to make it work however the guide is only for Linux by the looks of things. You can read up on that here.
