Rosegarden end marker

[Doug Regehr]

Hi,

I'm trying to compose a song with rosegarden, but the playback always 
stops after 104 measures.  It doesn't matter what the tempo is, whether 
I open an existing song or start from fresh.  I've tried version 11 
(which is in the main ubuntu repo) and version 12.04 from kxstudio, and 
the behaviour is the same.  Has anyone else seen this behaviour?  (Does 
anyone else on this list use rosegarden?)  Am I doing something wrong?  
Is there some sort of secret "end marker" that I need to move?
