Audio snap crash - Only soloution that I have found

Although I own X1 I made the decision to continue working with 8.5.3. Sometimes I need to do a bit of cutting, snipping and line up work on say a really nice bass track that has a couple timing issues or maybe work on a drum track. Anytime I have more than a few tracks with  audio snap enabled and at some point (though I cannot ever tell when) Sonar will crash. I can sometimes work on the same project for days without issues but always whenever some threshold is crossed with audio snap, it will crash Sonar - and always at exactly the same spot. When that happens, 8.5 will never play the entire song again without help.
 
What I discovered some time back is  that lo and behold, Sonar 6 will play the troubled file - always. So I open the file in 6, freeze the last track that I did audio snap work on (when the crashing began) and resave it as a new file with the sub title -whatever.frozen.cwp. I then reopen the file in 8.5 and it will faithfully play. It is a pain to do this because often certain settings are lost and certain teleported vsti's loose setups but at least the file was not lost.
 
Not to exaggerate, I have had probably a hundred or more hard crashes with 8.5 under these circumstances which leaves me with only the desktop and convertors buzzing through the mains, But restarting the convertors will fix that (most times but not always) and then I restart Sonar.
 
They really should not have left 8.5 orphaned with this horrendous bug.
