View all rows not updated properly if program deletes all rows

I'm using PgAdmin 1.6.1 against PG 8.2.0, both running on Windows XP.  I 
have a test Java program that inserts and deletes rows into a single 
table; I vary the operation of the program by commenting out various 
parts.  Before running the program, I open a view window on this table 
by selecting "View all rows".  When I configure the program to just 
insert rows and click the refresh icon, all the inserted rows show up. 
If I configure the program to insert then delete *some* rows, when I 
click the refresh icon, the remaining rows are properly shown.  However, 
if I configure the program to insert then delete all rows, clicking the 
refresh icon doesn't do anything.

If I go back to the main window and tell it to count the rows in this 
table, it correctly reports zero.  If I close the original view window 
then open a new one, it also correctly displays no data.
