Walkbacks - for information only

This is more for information than a proper bug report as I cannot find a way
to reliably reproduce it.  It's happened five or six times today but in two
different situations. In both cases I had a list of methods, either in a
MethodBrowser or in the PackageBrowser/loose methods, and was opening a
browser on each of the methods in turn, editing in the new browser and then
closing the browser. It looks like some kind of sequence problem but I can't
work out how, what or why.

The last w/b was

17:24:43, 04 May 2002: Unhandled exception - a
