Just got this Vista x64 up and running. Downloaded and installed the iTunes x64 version. When I run it, the window opens up is all black, only some of the words such as the file, edit and those stuff are white. I can't see pretty much everything else. Been Googling for solutions but unsuccessful. Maybe someone can help out here?
I guess I can say, I can live without iTunes, but I just depend on it too much to play music and manage them.

My Quicktime has the same problem on some sites. Take the apple movie trailer website for example. It's all black screen when I click on the trailer button to view it. Only if an external QT window opens I can watch it.

Anyone come across bugs or errors like these? Hope someone can help.
