Good call, Bill!

I had tried to simplify the code shown in my snippet. The actual code (which I
inherited) doesn't call the Contour procedure directly. The code within the loop
over images actually looks like this:

; Keep the color bar from erasing the classifications
!P.NoErase = 1
VSPlot, info
!P.NoErase = 0

I did not realize that Erase or !P.NoErase would have an impact on the
pagination.

It's a pleasure learning from you all.
