I cant use commas all of a sudden! Whenever I try to use one the cursor disappears...anyone have any clue why and how to fix it?

Do you have access to another keyboard you could try? There may be a problem with the comma on the keyboard. You could also go to Start, All Programs, Accessories, Accessibility, On-Screen Keyboard and try clicking the comma there to see if it's a keyboard or computer problem. If it is the keyboard, you can easily pick one up for under $20 and plug it in.

Thanks! It all of a sudden started working again..weird.
