I personally am completely confused about VMs. Now we have even one more :-)

No - we do not have one more, just an updated rebranded version as I did in the past to make it more Pharo like. On Win32 it goes like this: =========================== A) Andreas provided the official Squeak VM on http://squeakvm.org/win32/ Last official one is 4.1.1, I just gave it a new pharo icon ("lighthouse"), name and file ressource so one can see the VM version directly in Explorer. => unfortunately this is very outdated from 2010, no activity/response on Andreas side and no new Win32 Squeak VM maintainer stepped up AFAIK Even when outdated we still use this as the standard VM in the Win32 Installer (see Pharo1.2), I will reuse this standard VM for 1.3 too. B) Eliot provides the fast Cog VM on http://www.mirandabanda.org/files/Cog/VM/ Last SVN revision is VM.r2474, again anything I do is building the VM from subversion with another icon ("lighthouse with gear"), name and a file ressource so one can see the VM version directly in Explorer. This Cog VM is also in the Win32 Pharo 1.2/upcoming 1.3 installer so Win users can profit from Eliots work. After using the Win32-Installer one can (by using the different icon "lighthouse" or "lighthouse with gear") start the appropriate engine to run his image. I hope that we can get a better situation as soon as - the standard VM "A" is built right from the newest VMMaker - for "B" (the Cog VM) is either built from VMMaker or from Eliots SVN repo Bye T. -- NEU: FreePhone - 0ct/min Handyspartarif mit Geld-zurück-Garantie!
