View->Optimizer is greyed out, and un-selectable.
The Photos tab, bottom left, has Optimize->Geometric
(I find no tab for Optimizer) says:
"when stitching a map or when all is on the same plane you don't need to
optimize plane yaw/plane pitch. These variables should only used when
there are several remapping planes in the pictures are needed (e.g. for
patching a nadir image). For stitching images on the same plane, you
have only one defined remapping plane.
"
but all options in Optimize->Geometric all have y p and r, except "Custom Parameters", and nothing seems to happen when I select that option.
Oh, wait...when I select "Custom", the Optimize tab appears!
It seems to have selected p and r for the left photo, and y p and r for the right.
I will uncheck all 5, and optimize.
No...It wants SOMETHING to be checked to optimize, so I'll check the X Y Z for the right ("Active") photo.
Oh, yes! much better! The bottom edge is almost straight, and things look good enough, I guess... The sides are bulging out a bit, and the middle divider line is a bit curved, despite all three being "Vertical Line"s. Unless you can suggest some way of fixing these lines, I guess we're OK now...
Thank you!

Sorry! Although I fail to see how I could adequately explain what was not working unless I actually SHOW it...
