I've only had one crash so far (while adjusting parameters during playback to a 3rd party , 64-bit plugin [so, no Bitbridge involvement]), but I am experiencing an annoying bug; during playback, I sometimes cannot manually select an individual track or bus to, let's say, adjust its volume. I have to hit stop or pause on the transport.
I am also occasionally experiencing a problem with the ProChannel - after having a track selected, I will jump over and select a new track, but sometimes the ProChannel on whatever track I previously had selected remains in the left panel and I end up editing the previous track's ProChannel, instead of the new one that I have selected.
I'm running X2 64bit on a Windows 7 Pro 64bit system.
