I think I've found another bug, but it's very minor and doesn't affect playback.
First, click on the I button on the main ui or the View file info from the drop down menu. Now look at the title bar.
Now, press the shortcut key for View file info(ALT+3). Look at the title bar now.
It doesn't have the title in it, just a blue bar. (MPEG file info box + ID3 tag editor)
