This is on Mac OS 9.1 using the final 3.1 upgraded to alpha.
When it tries to recompile the updates into the image I get a walkback stating that "isSeparator" is unknown and it finally gives up in "recompile:from:".
Btw SqueakCentral...3.0 is VERY nice. However, the main menus are really poorly organized...especially after being used to the minimalist 2.6-8 non Morphic variety. The menus are very cluttered and seem to lump things like updating the image into "help" (yes I know that's how it was under 2.6-8, I just don't feel it should be under "help".) This relates to the various threads throughout the years about the newbie-experience with Squeak (I'm still a newbie). Maybe some thought should be given to reorganizing the main menu(s) into more logical (ok, maybe more expected (per Windows/Mac idioms) of menu groupings (sorry about the Lispish-parens)) If menu items were grouped in a more "standard" manner newbies (incl. me) wouldn't be so put off/frustrated by the Squeak experience. Maybe even give the user a "menuEditor" that would allow him/her/it to customize the menus to suit.
