I've noticed this recursion a few times. I chose a method in a RB and asked the RB to "rename method", and got this. I have the RB and Skins packages loaded.

This is still a problem in 3.6.
Bringing up a browser. Squeak hangs, eventually crashes because it's out of memory. Preferences for inboard scrollbars and hidden scrollbars are set. The problem is that the scrollbar keeps getting alternately hidden and shown, and there's a possible recursion:
