Kingston Bus Solo Issue

Recently I was working on two guitar tracks that summed to a bus.  When I solo'd the bus, Sonar Kingston locked up. Shut down, reopen Sonar and tried again, same thing. The song is playing along, I hit the solo button on that bus, instant lock up! Thinking it might be a plugin, I removed the last plugin I had added, same thing. I tried this several times and finally solo'd a different, non related bus. Sonar locked up! I rolled back to JP and everything seems fine now. Anyone seen this, or anything like it?
 
Note: This issue has been reported as a bug by TwelveTone, [CWBRN-42298].  Thanks Ken.   I'd like to keep the discussion going so we can help the Cake team track it down.
 
Any suggestions, help or ideas are welcome.  Thank you.
 
This issue was split from a previous post.  Here's a link to that post: http://forum.cakewalk.com/FindPost/3330625

FYI, Cakewalk's Dan Cate is looking into this one.  I'll pass on anything I learn.

Update: I received a message from Dan Cate.  He was able to reproduce this bug.  Hopefully a fix is in the works.
 
Thanks Dan.

I just loaded up the Javier Colon demo (which has 44 tracks and 18 busses) on my seriously underpowered laptop.
 
I can repeatedly solo different busses without a single lockup

Just to keep this thread up to date:
 
Apparently Dan from Cake was unable to reproduce the bus solo bug a second time.  I rolled forward to Kingston again and easily reproduced it so I sent him a dump file of the project.  We'll see what happens.

Paul you are doing great work here. I don't seem to have the bug but that isn't important. What is important is that it should be fixed. 

Thanks John but I'm not doing anything that anyone else wouldn't do, trying to help out.
 
I haven't heard anything back from Dan but I'm not sure that I would.  Hopefully, the Cake team is working on this.

What happens if you delete these rogue busses and re-create them?
 
It's not been unknown for a bus to become corrupt, though I haven't experienced this for many versions now

For what its worth, there are times where projects just get f'ed up with strange things happening.   Have you tried safe mode?  Try opening  the autosave copy or if you have versioning turned, open  another version.   Chances are the issue will go away.  You may never figure out what is wrong but at least you can move forward.

^^ I had this with a Metronome bus some time ago. Recreating them helped.
All the best.

Thanks Ken.

Update:
 
I worked this problem again last night and now I'm getting different results!  Previously, I had this narrowed down to the Sonitus Delay on a bus in the PC, out to a Sum Bus also with PC engaged.  Disengage these two PC's and no hang.  Now, I tried several other projects, (which hang on pressing a bus solo button so it's not project specific), and deleted the Sonitus Delay from the PC and it still hangs!  Also tried the new Lexington patch, same results.
 
I don't know why I got different results previously although during that test, all the PC's were disengaged except on the two buses mentioned above.  I'm almost thinking my projects are too big for these new patches!  On projects with lower track counts I have to work harder to get Sonar to hang, but it finally does.  Back to JP and everything is fine.
 
Any other thoughts?  Thanks.
