As there are no instances of these classes anymore, it’s an annoyance, as I’m wondering what is referencing these classes.
I just did a bit more poking and when I emptied the method dictionaries for these classes, many of them were garbage collected.

It’s not just our own classes, but I also see a lot of Metacello* and XML* class(-versions) in that list.

I will probably just try what you suggested and see what info I get in 3.3.3

Thx, if I’m still lost in a week from now, I might just send in a ticket for help :)
