?? 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.
