--- Comment #15 from David turbolad995@hotmail.co.uk 2011-07-16 07:22:57 CDT --- Still testing and updating this bug report with newer versions of Wine and newer versions of 1by1 Player - the same thing happens every time: you can only play one audio file and that's it.
If you try to do anything else with 1by1 Player when the audio track is playing, 1by1 just generates the error message - see the attachment "Error when using 1by1 Player version 1.74".
You can't play another audio track - you can only play ONE from start to finish, and that's it.
