This operation automatically changes the default folder which gets locked by Windows. This will be fixed (or rather modified) in the next release.

I've found that if I use the right-click Send-To menu to send to an .m3u playlist, once the playlist is written, I can't do anything with the folder it's been written into until I either:
a) close MM
b) send-to another playlist

This leads me to believe that MM isn't properly closing the playlist file, so Windows thinks it's open.

Anyway, should be a quick, simple fix.

Thanks!
