Never been a problem for me...I have SCREEN = OFF in my config of my development directory, and the main screen is only "covered by" the top-level, always available using debugger, minimizing top-level, etc...

However, a caveat is I'm not quite certain about NT, I have no test machine immediately available just yet - should have my own in a month or two, I hope...
