However, there are some broken bits in Squeak that will make learning Smalltalk difficult.
Most simple and important example I have right now is the well-known issue that the VM will freeze indefinitely if you input a long running calculation, e.g. x := 100000 factorial. The interrupt key doesn't work, usually. Newbies like me, like to experiment, and if the VM freezes with every typo, then its hardly worth using.
This is interesting because it does *not* freeze in my Qwaq-derived work image. Here the interrupt key works perfectly with no delay. I'll see if I can investigate. Andreas, do you recall doing anything to the debugger to fix issues like this in the Qwaq system?
Nothing I can recall. Also, when I try interrupting 100000 factorial in a 4.2 image with either a Teleplace or OpenQwaq VM I have no trouble interrupting anything. So it doesn't look like it's an issue in the image that is causing it. Wonder if there's anything changed in the support code perhaps...
Cheers,

I think there may be an error when trying to bring up the user interrupt dialog.
Pressing Cmd-. during "100000 factorial" does create a SqueakDebug.log file immediately, but does not show the debugger.

Found something: reverting #openInterrupt:onProcess: from the "mtf 2/5/2011" version to the older "sd 11/20/2005" version restores interruptability

... as does ignoring the CurrentReadOnlySourceFiles exception in the logging code. Levente?
