Well this issue has reared its ugly head again. I had submitted the error report in X2. Tried it initially yesterday with out issue. What I did different today was while the Console is undocked, I would move to different tracks and then back to the Master bus with CL in it. (Will also do it with Ozone in it, thus causing Ozone to flag the error, however for this test I deleted Ozone). The dreaded white screen appears and X3 shuts down with the Sonardpr.exe refusing to be shut down by the task mgr. I have to restart the machine. Logging out and back in will allow Sonar to come up but for some reason one of my midi controllers will not start (Akai MPD26). So a restart is my only recourse. Darn it!!!... Help??
