Preview Play button flickers, program crashes

[Judge]

When you compile your findings with my earlier ones, it may be that KeyRite is too sensitive to something in the file that it doesn't expect. Other audio/video processing applications that I've worked with "pre-curse" the file and if there's anything amiss - it reports "Incompatible File Type". That's a lot more user-friendly than the software crashing when it tries to process a file that it can't handle.
