Thanks for the explanation. However, I regard this as a serious bug: In my 
scores with 15 staves, there is about 2-5 cm (amount varies on each page!) of 
empty space left on every single-system pages, while the page is completely 
filled for pages with multiple systems. Thus, the last staff of the systems 
doesn't align at all and the page layout looks very amateurish and with way 
too little stretching.
If I increase the paper-height, the systems are stretched (so stretching IS 
enabled), but the remaining empty space on the bottom also increases (e.g. if 
I set paper-height to 40\cm, the empty space between the last staff and the 
footer is typically somewhere between 25 and 40 staff spaces!!!).

Unfortunately, with this bug it's impossible to create good-looking (i.e. 
print-quality) full scores. 

Does anyone know how to fix this problem, or at least where to look in the 
code?

Cheers,
Reinhold
