Beads can fall off abacus

Thanks for filing the ticket. I overlooked this in Tabitha's testing report... Now I just need to figure out how to reproduce it :P

 http://git.sugarlabs.org/abacus/mainline/commit/d0e39b9a2976e6a579136e196f9cd1d6086a1d1d seems to take care of the problem. Please reopen ticket if it reoccurs.

Walter please note here if you have it in a new version, so Daniel can incorporate it in a new build if desired.

Just seen that Abacus 20 should be the one...
