[Pharo-project] cogwin/Croquet (Win7) + Moose + very large models = crash (out of Memory)

Hello, I'm using cogwin/Croquet VM (last version http://www.mirandabanda.org/files/Cog/VM/VM.r2522/) on windows7, and today I had this probelm: when the size of the pharo image become so large the VM crashes with reason 'out of memory'. The same problem with previous versions of cogwin. Note that I use a PC with 8G of RAM, so it's really damage to have such a problem. Any idea about another VM working well on Windows and does not have such an issues? Any urgent solution? Thanks, Hani
