Really wierd PGAdmin/Windows Explorer bug?

Greetings!

I just ran across one of the strangest pieces I have ever seen in a piece of software.

I was connected remotely to a test machine set up at a customer's site.  The machine is running Windows XP and PostgreSQL 8.1.  PGAdmin has a connection to the customer's production database, which resides on another machine.  The database has a simple 3-column table that I thought has 22 million records, until last week when I found that a backup of the table showed that it actually has no records.  A member of this list introduced me to the concept of inherited tables.  There are 2 rules on the feedback table.  One says that if the charge number is less than 7000, then data should be inserted into the feedback_backup table and the other says that if if the charge number is greater than 7000, data should be inserted into the feedback_active table.  The feedback_active table's definition includes "INHERIT (feedback)".  The feedback_backup table does not have an INHERIT clause. 

I was curious about how much data was in each of the other two tables.  I opened an SQL window and issued "select count(charge) from feedback_backup".  In a separate window I ussied "select count(charge) from feedback_active".  The two queries were running simultaneously.  I already knew that "select count(*) from feedback" takes about twenty minutes.  I minimized my Remote Desktop window and moved on to other things.

Half an hour later I returned.  Neither query had finished, and the query timer in both windows had not been updated.  Task Manager showed me that every PGAdmin task was not responding.  Using Task Manager, I killed PGAdmin.

At the time I first issued the count queries, a Windows Explorer window was up.  It was showing the contents of a folder that had 4 filed: backup_feedback.bat, backup_in_pieces..bat, restore_pieces.bat and restore_feedback.bat.  After I killed PGAdmin, the names of the files were shown to be:
    backup_feedback.bat
    Ln 1 Col 31
    46250 ms
    46360 ms

With some idea of showing you what happened, I pressed Alt-PrtSc to get a screenshot of the strange file names.  On my machine, I started MS Word and pasted the contents of the clipboard into my document.  The file names were correct!  I tried using Ctrl-PrtSc on the remote machine, but the same thing happened when I pasted the image into my Word document: the file names were correct. 

I closed the Windows Explorer window and reopened it.  And the incorrect file names reappeared!

Can anybody explain this?  Should this be brought to anyone else's attention, and if so, whose?
