When I hit the key M (map) or L (quest log) key, the game crashes for a while, returns to the battle.net screen and returns to the game after a while. It takes several seconds, but gaming becomes virtually impossible, because the map is used all the time. Every once in a while the computer crashes completely, the reboot is necessary, even Windows cannot be resumed.
Reinstalling didnt work. Have made WoW UI reset, uninstalled all addons, updated graphic card drives etc.
Anyone? Anything?
