If you're running Windows XP, there is an easy way to 'fix' things, XP has a beautiful 'restore' feature. Click on start, then Programs, then Accessories, then System Tools to reach the System Restore tool. Pick the time you want to go back to [an hour or two before you had the problem - or a day or two or whatever]. It doesn't 'goof up' any of the work you may have done, will just go back to the time before the problem. Nothing will be deleted. Jocelyn in Ohio
