I had a problem with my computer earlier today when it stopped responding and froze. I could not get to the start menu so I had to push the shutdown button. When the computer started back up everything seemed to be working ok except the taskbar. The taskbar is frozen. When I put my mouse pointer over it the corsor turns into an hourglass as if it were busy and I cannot click on anything including the start menu. The clock is even frozen. I scanned for viruses and found one and it was deleted but that did not seem to solve the problem. Can somebody help me figure out what to do?
