Often, when not actually in a game (ie. in one of the menus), the music will suddenly make a small loop and my mouse will freeze. If I press ctrl-alt-dlt, my normal white cursor can roam free, but to no effect. If I press it again, my computer restarts. Other than that, there is no other way of interacting with the freeze. This generally happens when repeating motions: For example, I repeatedly logged in and out of Valkyrienet and this happened. Could somebody please help this poor, frozen soul?
