Wxmediactrl has no output on windows vista & seven

Hi, I’ve just tried installing ruby + wxruby from the following
installers and in every single one, the wxruby sample media/mediactrl.rb
doesn’t do anything after loading an mp3 file under windows vista and
windows seven. Funny enough, it works flawlessly under windows xp.

Could anybody help?


Ruby 1.9.1-p378 (RC2)
Ruby 1.8.7-p249 (RC2)
Ruby 1.8.6-p398 (RC2)
Ruby 1.8.6-p26 (Final)

I am also having the same problem. I am running wxWidgets 2.8.7 and
playback of mp3’s doesn’t seem to work on Windows Vista and 7.
