Re: set-window-configuration vs error-checking sub windows

The garbage-collection then creates the problem with the inconsistency between the two weak caches. Either the weak-lists are not working correctly or there is something which keeps holding references to the instances[1] .. Jan Footnotes: [1] Isn't that a general problem? Can lisp get at the instances?
