Problems with pause screen

I have a few problems with the pause screen on a game I'm working on. When you go into options, and select the 'full screen/windowed' option, it doesn't work. Also, when you customize your controls by pressing any key, that doesn't work either. The pause screen is a sub-application, and both of these options work when you run the frame alone, but for my game I have to have it work as a sub-application. Any suggestions on how to make it work?

If you are talking about going into the options screen during runtime during the pause screen, I don't know of anyway how to fix that. Its just the mechanics of the sub-application.

But for me, you can still go on full screen and then pause it.

Kind of hard to say as I don't know how you have things set up. Did you make sure that your subapp can share global values or something? (I forget the exact name of the option).
