Have you tried interrupting it? While you're waiting for Squeak to
respond, use the Cmd-period (Alt-period) interrupt to bring up a
debugger (and a new main event loop, if needed). From there, you may
still have a slow UI, but it should be fairly straightforward to see
what method is taking a long time to respond. (My money is on #hash,
but you never know.)

Good luck with it!
