Tom,
There is an inexpensive software application called "Go Back" that you might want to consider. It allows you to restore your PC back to a few minutes ago, an hour or so ago, or even days ago...you chose.
Comes in handy when you loose work...
The new MS Windows XP gives you this feature called "Restore"...if you are upgrading to XP soon...
Regards,
Pete... <img border="0" alt="[typing]" title="" src="graemlins/yltype.gif" />
