Hey Rhino, first an update, then I'll answer your queries...
After removing AV from .110, and getting it to work that way, I re-installed AV and it seems fine now. I have yet to re-install PN. Some things I tinkered with after the crashes started was skins, since all my homemade skins got wiped out in a complete uninstall of MC when trying to eliminate the problem initially. I've changed skins twice during the freezes, and it's possible a problem could be generating there, dunno, it's just a thought. I'm currently using Opus which I switched to just before re-installing AV and having it work now.
It would generally freeze just after playing the first song or near the end of the first song, but it did on occasion wait a couple songs before freezing but it was always quick, never more than five minutes before a freeze. And with my system it froze everything, not just MC. Ctrl-Alt-Del did nothing, it had to be hard reset and disk-checked each start-up, a complete crash. Oh, and I'm using 2.0.7.2, so I'll upgrade to the next one right now.
Thanks,
bb
