dropped columns

Hi all
I had this problem a while back, which I posted in the novices section:
---
With 7.3.2 I used
 ALTER TABLE job DROP x
 To drop column x

 The result is that column x is now a replaced by a column called
 "........pg.dropped.4........."
 exists in its place, and now my odbc connections won't touch the table.

This suggestion was made in reply:
----
You need a newer version of the ODBC driver (one that understands about
dropped columns).
----
However, as far as I can tell I'm using 7.2.5 which is the latest
(according to upgrade wizard pgadmin). Any hints?
