?? Full browsers of Hierarchical browsers??

The reason I ask is that there is a known problem with the later
 which will sometimes confuse the browser.
I usually see it when creating a new class.
You may have found a new way to bump into it.

Invalid drawing panes "latch up".
To fix them it is necessary to not only fix the underlying problem
 but to release the latch via:
the red menu>debug>start drawing again.

For browsers it almost always easier to just start fresh.

If you are willing to put some effort into getting this tracked and fixed,
please add a report to mantis
 describing a way to from a fresh start reproduce the problem.
Enough specifics to reliably reproduce the problem
 is a starting point for others to explore and play with it.

Here are the FAQs:

FAQ: Is this a known issue ? Where is the place to report bugs (or check if
some have already been raised) ?

The best place for this info would be to start a
Mantis report. (You can get a mantis acct freely and
easily).

A good place to start is:

http://bugs.squeak.org/my_view_page.php

Mantis provides a patient persistent way to focus on an issue.
I use it to accumulate data on a problem until a solution can be found.
It provides a place to alert the community to a problem;
-accumulate facts and clues from the analysis;
-publish preposed solutions and get feedback;
-get solutions harvested and included into the main stream.

This FAQ is available at the Squeak wiki site.

They were not Hierarchal browsers, AFAIK.  Just the standard browser
you get from World menu -> open... -> Class browser.

Perhaps?

Ah!  I didn't know that, thanks.

Yes, that did work out well.

Thanks Jerome.  Mantis has always been mysterious to me.  I will see if
I can duplicate the problem and add a report.
