I just compiled 2.0 (on FreeBSD) and there still seems to be a bug with the PlayWithMe-4 demo. That's the online Oopsla article and when I click on the right arrow 'go to next page' in the control panel (to the right of the '+' button), Squeak just hangs ... (I have to kill it). This bug was also in my 1.31 and 1.19 version, I believe. If somebody is interested in this, and can give me a clue on how to debug this, please contact me.
