Problem: List view collapses upon change

Hi everyone reading pgadmin-support,

PgAdmin is a very fine tool.

There is a single erratic behaviour which I'd love to see fixed,
to make it an even more valuable tool.

When I'm changing the properties of a column,
the tree on the left side of the pgadmin window
collapses and I have to navigate all way down again.

(This has probably been reported before)

Environment:
pgAdmin 1.16.1, postgres 9.2, osx 10.6.8

Description:
Changing a column definiton results in the tree on the left being collapsed.

How to reproduce:

Navigate to a column
aka Server Group > Servers > $server > Databases > $database > Schemas > $schema > Tables > $table > Columns > $colum

Invoke Properties on that column

select the Definiton Tab

change the value of the Not Null checkmark.

Hit the OK Button

Actual Result:
The tree view on the left collapses

Expected Result:
The tree should not collapse,
but should instead display the very same focus on that column
