Well, the only thing I can remember is the crash(es) occured during audio playback (stereo flac source, converted to 6 channels + EQ), with the G-Force visualizer running, when I was about to import & tag some new audio files... So the issue may be related to many things, including the visualizer...
Anyway, please note that my initial post was not a complaint... In fact I haven't seen MC crash for years while on the 'Stable' update channel, but several since I changed to 'Latest'... That's all I can say.
