alright so there is a problem with my task manager, i am running windows xp home edition and when i open my task manager to turn off programs and shut down processes on the process tree, it puts an icon at the bottom of the screen like a box with a green leveler that goes up and down with computer processes. My problem is that my task manager does not open and when i go down to click on the green box next to the computer's clock it disappears....Any suggestions????
