I've stuck a version (5.8b9) of the cocoa based os-x squeak cog JIT based VM in my experimental folder. http://homepage.mac.com/johnmci/.Public/experimental/Squeak%205.8b9.app.zip Changes are: (a) Slight changes to the Open/GL code in hopes to make it work better on 10.5 machines (b) Add ioUtcWithOffset (c) Application quit menu, quit from dock, or window close now triggers a Areithfa Ffenestri window event saying the window is closing. Most images (I guess?) look for that and prompt the user to save or not-save the image and/or quit. People producing Squeak Images should confirm the behaviour is what they expect. (d) print problems with cmd-shift-key not correctly working CMD-SHIFT-n as an example. (e) Code sign app -- =========================================================================== John M.
