care to explain that phenomenon!
It that by design or are you confusing the word desktop for window.
Desktop is the screen you see when you have nothing else running. It would be where you desktop picture would be and would most likely have an icon of the hard drive on it.
Window is what opens when you launch any application on your computer.
Perhaps you are referring to Spaces. Is that it?
I'm new to Mac and have the multiple desktops. When I read a document in Word and want to write comments in Word on a different desktop - moving between them, I find that if I open a new desktop and click on word icon, it just reverts back to the original desktop
