Guys even if one day we may integrate petitparser (so far I do not see why - but do not comment). We need an up to date configuration because we want everything with configuration because we want to bootstrap 4.0. Stef

I have two machines, both running Windows XP with SP3. On one of them I have a successful load of Pharo (actually it's a distribution of the Moose system, but that is just an application built on Pharo 2.0). This loads successfully when I double click on pharo.exe. On the other machine, the same action produces an immediate message: 'Pharo.exe has encountered a problem and needs to close'. Just in case this was some problem with Moose, I have just downloaded the latest one-click installation of Pharo 2.0 for Windows. This displays exactly the same behaviour - an immediate fail when I try to start it. > > I have tried to work out what may be different between the two machines. The one which will run Pharo has an Intel Celeron processor, the other an AMD Athlon XP (yes, they are both pretty ancient!), but I can't see why that should make any difference. The one curious thing is that Windows Explorer displays the type of the Pharo2.0.image file as 'Squeak image file'.

Annick You cannot expect people to respond to you if you do not provide full context + information. On the long term people will stop to reply to you. Repeat after me: which image? which OS version? which vm version? I think that we are pretty nice people but do not force us to always ask the same questions. We are all busy.

It not saves all the parts, just the AssignmentNode, MessageNode and ReturnNode. (other intervals like the ones corresponding to TempVariableNodes for instance are not saved).
