[David Bobroff]

I have an odd score I'm copying for someone.  In it, there is a section 
in which to top staff is notated in 1/4 time and the other four staves 
are noted in 5/8 time.  I have managed to make it work by altering the 
four lines in 5/8 but I would rather modify only one part.  I have not 
managed to get it to work.

In the example below what I expect to see is a measure of two eighth 
notes followed by a measure of a quarter note.  I'm getting two eighths 
and the quarter in the first measure followed by a small extension of 
the staff lines beyond the barline.

Am I doing something wrong, or is this a bug/limitation?
