Ken Brown was lucky enough to figure out that the 3.8.19beta1U VM won't launch on a 4GB Mac Pro when you have 27 other applications running. The 3.8.19beta2U VM has a fix to work around mmap issues when the operating system would rather load you at the 42GB boundary, versus our suggested 512MB. I've posted the new VM in the usual places via ftp or my idisk at http://www.smalltalkconsulting.com/squeak.html -- = = = ======================================================================== John M.
