No worries, if you do experience it on 5.0.2 when you end up updating the team would still be interested in a debug log to troubleshoot.

Hmm... Given the issues I've had with this version, I'm not sure I'm ready to start playing with betas. Since it's only a minor inconvenience and things are relatively stable, I'll leave it as-is and wait for the next published update. Thanks for your response!

Please try this with the latest beta: viewtopic.php?f=30&t=86639&sd=d

If it still occurs, please capture it in a debug log (step 4b) and attach the log to a Support Ticket: viewtopic.php?f=30&t=86643

This will help a developer analyze why this happens in your setup.

I've got my keyboard's play / pause media key mapped to Playback: Play/Pause. I've changed all other Play/Pause to Ctrl+P to avoid interference. There are no other shortcuts mapped to the play / pause media key.

Whether the song is playing or paused , using my keyboard's play / pause media key resets the song to 0:00 about 1/3 time.

Any thoughts on why this might be happening?

I'm on MWM5 5.0.1.2433.
