Soloing Acting Strange (Not turning off correctly)

That is really strange and I've hardly a clue.  Has anything changed in your system setup or is this a new install?  How long has it been doing it, and has anything unusual happened lately?

Just want to make sure your old install was "X1c" and not any of the other before because "d" has to be applied to "c" update only and  "c"  can not have any of the quickfixes applied to it.
 

Is it happening in just one project or different projects.  You may have a currupted project.

Yah I hear ya I been burned the same way saveing currupted project files.  Then I would have to correct the project because the older versions were also currupted. 
 
1st You'll need to  start as fresh project to make absolutly sure you don't have a project problem . 
 
If you don't have a project problem then you are going to have to do a reinstall or disc image restore because you system is currupted.
 
If you do have a project problem then you will need to copy the contents of each track into a newly created Project.
You can save presests for plugins but I would not save track templates.
 
That would be the quickest way to correct a problem that popped up out of no where.
