I've not seen the severe hanging up since I last posted, until just a few minutes ago. Unfortunately, I did not have Avast turned off, so I can't say for sure that Avast does not play a part. However, assuming this does have something to do with Avast; what is the resolution? I can't really justify running without AV all the time. I try to pay attention while browsing, and am as careful as I can be, but I feel better with an AV running, just in case. I am certainly not the only person running Avast and MC on Windows 7 x64.
As for the recent hangup, I had recently finished ripping an MKV and opened MC to look for something. MC had not been running, so it had not had a chance to import the file. I suspect it may be the import that is causing the hangups, but that's really just a guess. Log attached.
I'm not sure if this is relevant, but it seems excessive...
