Forum: wxRuby 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?

Thanks

Ruby 1.9.1-p378 (RC2)
Ruby 1.8.7-p249 (RC2)
Ruby 1.8.6-p398 (RC2)
Ruby 1.8.6-p26 (Final)
mingw32-ruby-1.9.1-wxruby-2.0.1-setup.exe

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.
