Well, maybe not break, but definitely make unusable for me with no way
to back out that I am aware of.
First, install the Connectors package
then, create the fully-connected graph that I create in:

Now, try to disable any kind of user interaction for edges of the graph
by doing:
NCAAConnectorMorph allInstances do: [:ea| ea lock: True].
Yes, its the wrong syntax. Yes I'm stupid. But Squeak is now permanently
locked, and I can't get around it except by force-quiting that I can see.
Squeak appears to freeze. numerous cmd-periods bring up a buncha
"NonBooleanReceiver: proceed for truth" messages, none of which can be
interacted with (not close window, not click any button, etc) and
eventually cmd-period doesn't do anything either. No menus work, etc.
Clicking inside the Squeak window actually slows down the Mac GUI when
dragging the Squeak window for a while. It seems clear the interpreter
is still running, but interface via the GUI is hosed.
Eep.
In case you were wondering, I was trying to see if I could disable
mouse-interaction with the edges of the graph as a way of speeding up
and making more reliable, interaction with the nodes...
