[Moose-dev] Old vm in One-Click?

Hi I am looking to release a new version of the fuel extension to export/import. This version speed-ups the time to export, around 15% in my machine. Now, my problem: I dowloaded the one-click file, 4.6 build 461, and Windows is my platform. There, one test fails. But it is green if I open the same image in a more recent vm. - in one-click: Smalltalk vmVersion.. 'Croquet Closure Cog VM [CoInterpreter VMMaker-oscog.51]' - in my vm: Smalltalk vmVersion. 'Croquet Closure Cog VM [CoInterpreter VMMaker.oscog-eem.56]'. Is it possible to update the cog vm it is used to deploy the one-click? Or it is not important? Cheers, Martin
