I have had incredible stability with X3e but I just started running platinum today and already Sonar crashed 3 times at different seemingly random spots.    First time was during a normalization of multiple tracks, secondtime I was just perusing the tracks with faders and solo buttons and third time I wasn't doing anything...   I will need to dig in further but this is disturbing for me.   Stay tuned for more info.  Meantime, anyone else load Platinum and experiencing issues like this?
