How can i restore my task manager to 'normal'. I left my Pc running over night, when i looked at it today, it seemed to be running slow, so i thought i would look at the task manager and see whats running. However when i click ctrl+alt+del, all i get is a large screen that shows the CPU ussage, it doesnt have the ususal minimise, etc buttons. I can't right click onto it on tha task bar either. I have re-booted my PC, run spohos which hasnt found anything etc. any ideas?
