I will try too. I retried from 10095 during the sprint at my place. but now I will retry from 107 This was when we got the problem with lukas removal. and as you see I did not update the log This is the last time I do update from bern (because of this caching proxy I could not test directly). ------------------------------------------------------ update10118 - fix script loading broken.

excellent then these methods could be pushed there. John it looked to me that you have access to VMMaker so could you add these methods there and I would remove them from the core.

I tried to update the last core image (107) from the gforge. But that one stops after update 120. (blocked in a semaphore). Very strange.

What about a "Pharo/Smalltalk Beginners Workspace" with colored text and some interesting expressions to evaluate (or just hyperlink-click for a simple doIt/printIt) This should start with simple expressions, unary, binary and keyword intro up to some high level code or cool demos (turtle graphics, ....).
