I've stuck a version (5.8b4) of the cocoa based os-x squeak cog JIT based VM in my experimental folder. 

http://homepage.mac.com/johnmci/.Public/experimental/Squeak%205.8b4.app.zip

I spent the last two days becoming very familiar with Open/GL and rewrote the display logic to use 
Open/GL.  I am still doing some further optimization, but people should test this version and let 
me know what they find. 

Other Fixes. 
I think the control-arrow keys should work now, someone test this and let me know.
