Not responding

It actually does work if you open a first file and work with it but if you try to play multiple files in the same time so that you can later arrange them on your monitor just as advertized on the first picture , the app stops responding .. And too bad cause the app has a few cute effects too and a pretty decent layout with easy to use controls .. But again, as i said as long as youre only playing one file at a time..
If anyone knows if that could be fixed or if anyone can tell me what am I doing wrong or what am I not doing , pease let me know ..
