Hi Lyn

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?

The error is from the MessageBrowser, the MessageBrowser registers itself

for every class change (method added/removed) and tests if this added / removed

message should be removed/added to its lists.

Do you have any MessageBrowser open ?

- a sendersOf or implementorsOf

- if so,�� what search term is used in the browser (see window title)

I tried to recreate this error but all I could get was a MessageBrowser with

"nil" entries - no exception was thrown.

��

Thank you.

Lyn
