What a concidence, Chuck.
I also was busy today building a small panorama picture, consisting of
2 frames only. And I also have always used PTGui, but today started
with CS (version 2 in my case).
It worked like a dream: I could just accept all default values
suggested by PS.
Here is a small version of the result (next years X-mas card, perhaps)

Pictures taken with OM-Zuiko 90/2 on E-400. Difficult to focus because
of the stopping down and the lack of focusing aids on the matte
screen....
