I was using DrGeo for the first time from the bundled release 11.08 on
Windows 7. About 30 minutes in I drew three equally intersecting
circles, added a reflection line with each circle reflected. I added a
free point with a middle (I think to a circle) and was trying to add a
locus.
When moving any of the points defining the circles I am getting a dozen
or more cascading MNUs down the screen. Moving the reflection line
still works okay.
The error occurs in following method...
DrGeo>>updateDirtyCostumes
self presenter tool costumes do: [ :each | each update ].
self area changed
In the debugger inspecting "self presenter tool costumes" returns nil.
While I can't judge whether returning nil is valid here, as a Smalltalk
newbie what I am really interested in is:
1. The semantics of sending a "do:" message to nil. By the principle of
least surprise I would expect that it would do ...nothing, whereas here
it tries later sending the "update" method to it.
2. Why in lines 0027 and 0641 is the "do:" method received by
OrderedCollection and not UndefinedObject? Actually I can't see "do:" in
the hierarchy of UndefinedObject, so why does UndefinedObject not raise
a MNU for "do:" ?
The image with the error is available at...

below. I wasn't sure how much of it to cut or leave, so I've left it all.
