Sonar Crashes after moving Softsynth/Midi tracks

Good Day all,
 
I'm having a recurring issue, albeit somewhat randomly, that may or may not be the result of the current and many upgrade variables, I had previously reported symptom on forum, with uncertainty as to what I had done specifically to cause it. 
However, most recently I found, somewhat specifically, after I changed the order/position of a Softsynth track (with midi data in it), either in the console or track view within a group of various audio and synth tracks, upon starting play, control will subsequently lock in continuous play, (mouse remains active) and the audio engine stops and wont restart, requiring closing project "x" file, which then crashes Sonar directly into Windows, i.e., it doesn't invoke the Cakewalk/Sonar problem reporter, which sometimes happens in other crash scenarios.  Windows reports Stackhash error
 
Current work around, not to move Synth tracks from the position they reside or were created in.
Any feedback is appreciated.
 
Cheers
John Egan
