Hi, It appears that, when redefining a class, the class options that are not specified are left as they were in the old class, rather than reverting to their initform, as one would expect. All implementations seem to agree on this, so I'll assume it's standard behaviour. I've added a kludge to the metaclass' shared-initialise, which seems to solve this.
