Hi Jeff
I'm guessing that there must be
something out there at measure 115.
To quickly find the last event in your project, in the
Track View select
Ctrl+End.
If there is something out there, even an unused MIDI note, SONAR will include it as part of the project. To be sure of removing whatever is there, try selecting the measures you want to remove again, but this time select
Edit>Delete Special and check all the options available, as well as 'Delete Hole'.
To see if that's cured your problem, place the Now Time back
inside the project somewhere and hit
Ctrl+End again.
