I have this problem stated above, it came when I installed Litestep and shellon v2 on a pc with win2k3. What happends is that when I go in to menus with sub menus, or "side menues"(like the 'File - My status' menu in MSN messenger) with the mouse, this process called csrss.exe goes crazy on me, practically eats up the few mhz my cpu provides. However, sometimes it goes back to normal, but sometimes it don't, and when it don't, I have to restart my pc on the power switch. If I go in to the menus with the keyboard, nothing abnormal happends, though its a bit more annoying. Anyone got any clues, and would share them with me, on how I could get rid of this problem, would make me a happier man. // Alex

it should be a known ms problem. it's something with the menu transitions. try disabling the menu animations ;)

Hmm.. yeah thought of menu animations, but it doesn't help. But thanks anyway for the reply.
