I have a project that I've been working on for a couple of months which used to stop at the end of the project.  For some reason that I can't determine it no longer does and keeps playing ad infinitum unless I hit the spacebar.  All other projects work as normal.   I have unchecked and rechecked the "stop at project end" box in options and searched for any midi or audio data for hundreds of bars in the track view with no luck.  Not a deal breaker for sure, but annoying.  Any suggestions?
