Hi Bob,
Thanks for the help. Adding self changed to the end of the method solved the problem.
Your code seems to make changes to destForm, but nothing in this method tells me what causes destForm to actually appear on the screen. In addition to knowing how often this method is called, knowing how often #drawOn: for the calendar is called would give you a more complete picture.
The whole mechanism of how morphs work, are drawn and such is a mystery to me. I admit I haven't looked very much but is there something I can read that will help me understand the big picture of how morphs work?
