Cannot open any file.

[MidnightThunder]

Trying to open any file (at least any midi file) to add it to a playlist doesn't work, I don't get any error and the file isn't added.

Thank you for your report.
I have tried to reproduce this bug, but I can always add files to the playlist. Can you provide more information about this bug?

I think I have found the problem.
Files with an uppercase extension are not opened correctly by the program.
This problem will be fixed in the next release.
