Pavel was your image saved with Cogit? Because I cannot open it with my old slow cocoa vm.

BTW igor and henrik are coding like nuts floating point support with nativeboost. No need to have a float plugin. They seems to have fun like kids with a cool toy :).

Re: [Pharo-project] Some bugs

Hi Michael, I did in recent past and can renew help with 4) which is an immediate cheap solution compared to 5), but as you have seen in 2) the solution is not universal. On thing to remember with Decompiler, is that it sounds like a visitor pattern, but some very important features are sometimes implemented on the node side! This does not help understanding the too much complicated code (simple browsing is void, you often need debugging).
