Levente Uzonyi uploaded a new version of Tools to project The Trunk:
http://source.squeak.org/trunk/Tools-fbs.339.mcz

==================== Summary ====================

Name: Tools-fbs.339
Author: fbs
Time: 11 April 2011, 11:49:31.167 am

Ancestors: Tools-fbs.338

MessageSets open when earlier versions move the messageListIndex instvar from Browser to MessageSet will break without this change, because nothing explicitly sets the messageListIndex to a sane (non-nil) value. So we lazily keep things working: when someone next clicks on a message, the instvar will be set, and everything will work.

This does mean that the existing MessageSets will lose their place, though.
