Hello,

I'm running pharo 4 and I'm having a problem. I recently renamed a

class using the rename: menu item in the standard system browser (I

believe it's called Nautilus) and now I am getting uncaught exceptions

whenever I add or remove a method (three debugger windows pop

up). Here is the stack trace; any advice?

Thank you.

Lyn
