Launch popup window in front of fullscreen?

I have a fullscreen flash .exe file. I want to be able to use the fscommand “execute” to launch an application “in front of” the fullscreen without escaping from the fullscreen. So it’s like fullscreen with popups. I don’t think it can be done, and some extensive research backs up my hunch, but I thought I’d run it by here and see if anyone has accomplished this… thanks in advance, the flash advice on this site is the best I’ve ever seen.
