I know this is well known, but when I build an application, most of the time it will appear as a white screen. Also, when I try to Build and Run, it will tell me that I need to build it as a project first, even though I already built it as one.
In addition, when I try to switch frames in a game I made (Please login to see this link.) It will change music but not the picture. I think this has something to do with jumping to a frame that plays samples.
