I was thinking the Window Control object, but nope, nothing there. You could try playing around with subapps maybe. Or you could have two separate applications, and have the first one launch the other one at the end of the frame, though that does seem a bit unpractical.
Sorry if I'm asking, but why would you want to do something like that anyway? =P
Thanks for the replies, guys. I really didn't think it would be a big deal but ah well. Seems a bit silly having another app just to do that so I'll have to bare with the window frame for now.
