Hello.
When projecting a panorama with the panini general projection you can zoom out of the cyllinder in the preview window by manipulating the projection controls.
While you would expect to see at most the exterior wall of the cyllinder what you (or at least, I) get is a crazy web of what seems shoiuld be cyllinder mesh lines.
It's not a big issue, just that you don't see how the image will look before stitching.
My closest guess is that for some reason the cyllinder mesh backside warps through the camera view-point and back on into itself. This is just a guess.
Images will be accessible for 6 months.
NOTE: all puns unintentional.
