Still doesn't work properly for me, with or without the Media Manager. I don't have the Media Manager installed currently, and, for what is installed, it was working without hanging until recently, and I can't tell why. The only thing I can note is that I had a 'bad' install (the installer hung, but it had installed everything) and I think it didn't install/configure whatever causes the hanging.

Still want an answer. Let me know what they tell you.
