Quicktime gave me a hard time, so I had to manually search and destroy it.
But now it's back, and behaving.
For now.
For anyone that's interested, there are alternatives to QuickTiem and the other major offender, RealPlayer.
Google for "Quicktime Alternative" or RealPlayer Alternative" - they are real programs, not just fakes or programs that say they are alternatives, that's what they're called.
They do everything the "real" one can do, but are much smaller and faster.
Basically, it's WMP Classic with extra codecs and add-ons.
Back on topic (slightly) I agree about SonicStage, that's the only thing stopping me from wanting a Sony player.
Players that only play rare or obscure formats, or only about 3 formats of music, really get on my nerves.
