RussellS, when your PC crashes, is there anything in the Windows logs? I wonder if it's not hardware related? Video/sound card drivers? Hard disk failing? I once had a corrupt hard drive that whenever I played a certain track, just one specific track, MC crashed the PC. Turned out to be bad sectors on the hard drive so I replaced the drive and haven't had a problem since. I can't remember if I ever tried playing the track in a different audio player or not to confirm that MC was causing the crash, I was more concerned that more sectors would fail and I would have lost the entire drive's contents.
