I wonder if anyone else gets this? If I close Sonar with a track in record mode, it crashes. XP tells me it has a problem and has been closed down although it leaves the midi indicator in the sys tray. Restarting Sonar and closing again clears the indicator from the tray. Not really a problem because I don't lose any data (athough I would if I didn't save after every record - old habit) and it doesn't crash any other time. Curious though. It did the same under Win2k but never under 98SE. I suspect it's because Sonar disables disk caching and holds a file open for record armed tracks. Does anyone enable the read and write caching? - Sonar 1x disables it by default, what does Sonar 2 do? I also have my drives write caching disabled in hardware properties - I've seen it as a recommended tweak and I agree with the reason for it but what does anyone else think?
