--- Comment #6 from David turbolad995@hotmail.co.uk 2010-12-01 19:13:45 CST --- Try opening .mp3 files in 1by1 Player with Wine version 1.2 and later.
See if you can close 1by1 Player without any problems.
I can't get it to work and I'm using Wine version 1.3.8 - all I'm doing is dragging and dropping mp3 files into the player. It used to work, but since both Wine and 1by1 player have been updated regularly, 1by1 player no longer works in Wine.
