On my system adding a supported file into the samples folder causes the application to stop working. I've got the following simple code:
hide on : curs off : flash off : cls
Print "Hello World!"
This works ok, however when I copy a file (1.wav or 1.mp3) into the samples folder it stops the application from working. It compiles, but just shows a black screen. If I rename the file to an unsupported file extension (let's say .raw) everything is back working.
