pgAdminIII performance issue

<div class="WordSection1"><p class="MsoNormal">Just installed pgAdmin 1.22.0 on a new desktop when when I noticed some
basicqueries started running extremely slowly.  I went back and installed 1.18.1 (which was being used on my previous
desktop)and ran them concurrently to better attempt to understand what is going on.  The following describes the
issue:<pclass="MsoNormal"> <p class="MsoNormal">pgAdmin III v1.22.0 (standard install/no build) running Windows 7, 5
geni5/8GB ram, Gigabit networking.<p class="MsoNormal"> <p class="MsoNormal">Here are the results of running of two
versionsof pgAdmin running on the same windows desktop against the same backend server; The two have very different
