I've used Sub apps in a few other game's i've made in the past, and they've worked just fine.

But all of a sudden in this game im currently working on, whenever I go to create the Subapp and make it visible with options with Popup Window and Modal selected, you can hear the sub app music playing, but you cannot see it at all.

The weird part is, when its not set to popup and modal, you can see it. That doesn't make sense to me.

Any ideas what I could be doing wrong?
