I forgot my admin password to log on to our PC, went to Dell Comm. Forum, did a search and got the answer I needed (again). Imagine, the answer was in one of your posts!! Dell SHOULD have you on their payroll, in addition to the virgins promised you if you die at the keyboard!!
Again, thanks a lot! I don't think I've ever had a problem you couldn't solve.
Hope you have a great Fourth of July and a fantastic summer!!
