After I had posted the
Play/Pause fix using pjn123's sc_PlayPause.maki, I found a faster fix.
All you need to do is overwrite the skin's original play2pause.maki file with the one in the attached zip archive. You do not need to replace any line in any xml file.
The source of the attached play2pause.maki is FrisbeeMonkey's
Play-to-Pause script to which I applied
SLoB's fix.
