Thank you so much for getting back to me.
As soon as I click on Yes ( to save it), the pop-up goes away, but nothing else comes up to allow me to give the project a name or do anything else. The same when I click on the menu items. The page seems to blink, but nothing happens. I've kept the screen up all day because I don't want to lose the work I've done on it, so I suppose you could say I've been waiting for hours. I just now tried to Burn again, and got the same message about saving with the same results.
