My current project ends on bar 181.  My Ctrl-End command takes the Now Time Ruler out to bar 190 beat 5.  I cannot find any data out there.  I have tried the Ripple Edit All command from bar 181 out past bar 190...no difference.  I have looked at all of the individual track's Event Lists and nothing goes beyond bar 181.
 
What could I be missing?  Thanks for your input.

Automation?

Hidden or archived Clips/Tracks/Busses?
Automation on any of the above?
Meter/Key changes?
Tempo changes?
 
There is ALWAYS something there, making Sonar set the end of the song.

I once nodded off while working on a song and I woke up a measure 4,621. I've posted the same question but there seems to be no way of stopping it.
