OK, my mistake, but maybe this will help someone else.

I looked at the way I had named the other Desktops, and saw I was using the variable that holds the Menu's name. I did this a while ago, totally forgot when I set up the most recent Desktop, and so just typed the new name, in plain text.

It seems this not only fouls up that Desktop's (screen) name, but also the others!

When I fixed the new desktop, the others resumed normal operation.

Hi!
I was working in Dexpot, creating one new desktop and giving it a customized (screen) name.. Suddenly, I noticed that all the desktop screen names (lower right corner on my setup) had become identical, to the one I just created. As well, the names stopped changing whenever a different desktop was selected.

I went back to the default desktop (desktop #1) and gave that a new (screen) name, to see what would happen. Now all the other desktops acquired that (screen) name, as well. I didn't knowingly do anything to invoke this change in behavior. Until an hour ago, everything was working 100% normally.

I say "screen" name, because the name for each desktop on the pop-up menu in the Windows 7 TaskBar still displays correctly -- this is the name following the circled desktop number.

How can I recover from this problem?
