HWA with Fraps and Sub-Apps

Has anyone tried using Fraps in a game with HWA and Sub-Apps? I have an issue where I open a Sub-App (a pause menu), and Fraps grabs the Sub-App separately. And If I'm in the pause menu for too long, the game crashes when I try to close the menu itself. Does anyone know about this? And if so, is there another way to do inventory menus? I'd like to be able to record my game using Fraps, but I won't be able to do it if this keeps happening.

Also, is it just me, or do Sub-Apps not work in full screen mode?
