While playing Soulstorm's campaign (it also happened previously on DC campaign) my mouse cursor's image frozen in the middle of the screen and the real cursor is still active but becomes invisible.
Reloading the game or restarting the mission doesn't fix the problem. It makes it extra harder because I have to guess where I'm clicking with my invisible cursor.
Anyone knows how to fix this annoying problem? This happens at random time during campaign play.
