So whats the deal with Sonar? It took me 5 minutes to find a major bug that crashes the program every time. Send me a link and I will send you the file. In a nut shell I use a midi channel to turn on/off and other control codes for aN outboard TC electronics Voice live unit. If I open the midi track in question and drag the curser over the window-BANG! crash. For this is quite serious since all my performance files have midi files dedicated to control code only. The good news is I have never trusted Sonar not to have buggs when new versions come out. I left on X1 and it works ok. It sees the new plugins but I suspect they may crash if used in X1. So how soon will the fix be out?

Have you installed the Quick Fix (standard question)?

Does this happen on every type midi track, or only tracks that just have controllers only in them?
Plus, what do you mean "Drag the cursor over the window?"
