The Context stepping mechanism in Squeak was never designed (we're talking 1981 here) to negotiate process switches (which any window creation entails) properly.  It checks for and handles only the special case of "halt".  If anyone out there wants to submit a fix for this, we'll gladly incorporate it in the next release.  Otherwise, we'll add it to the list of desirable future enhancements, and I'll try to put in a test that will cause a more graceful and less catastrophic failure.
