File name disappears when editing

[petersmall]

Have just installed Lion and find I cannot edit file or folder names without them disappearing.
I click on the file (or folder) and press return to edit and the text just disappears - although, if I type a new name, this new name appears when I click on the desktop.
Why can't I see the text while I'm editing?

I've finally found the answer; it's been driving me nuts for six months!
If Finder is assigned to a particular desktop, it is the only desktop on which the file name can be edited without disappearing.
