Sometimes after developing a diagram for a while with Auto Stretch Pools on, the pools are too long for the content. How do I get the pools back to the correct length? I tried turning off Auto Stretch and manually putting the pools back to the correct length, but this caused complete chaos - one of the pools ended up more or less infinitely high, then when I tried to resize it back to normal BPVA hung completely and I had to terminate it.
