I'm not sure if this is where I need to ask this and I apologize if it is not right. I had a virus on my computer and could not get rid of it so I had to reformat the hard drive. I used my Windows Prof disk to do this and after it was finished installing, I noticed that when I click on a dialog box Title Bar and drag it across the screen, the movement is not smooth at all like it was, it is now very "jumpy" like it is trying to catch up. Does anyone know if there is a default setting that needs to be changed to correct this problem? I can't use my computer this way, it is driving me nuts. Thanks in advance for any suggestions.
