Andreas,<br><br>Thanks for the help.  For some reason I was still in non-squeak mode where I was thinking that I would need to rely on getting the help of experts instead of, *duh*, reading the code myself!  I read the code for BalloonCanvas and looked at the old WatchMorph in an earlier version of squeak and I found the optimization and work around you mentioned.  It takes some time to get used to have all the source available I guess!<br>
<br>Thanks for your help,<br>Jeff G.<br>
