corum closes

Corum randomly closes itself sometimes and I have no idea why. It makes no difference what activity Im doing or where I am, it will randomly close completely, no error, just like if I had clicked "Exit to desktop". It will close randomly, sometimes I can go for a few hours othertimes it closes within half an hour. The game is still completely playable and I have no other issues, I just load up the game and log in again. Its just annoying and I wish I knew what was causing this erratic behavior.

Anybody else know how to fix this or is anyone experiencing the same problems?
