David,
Was able to reload images with no problems except on one (made with one of the more recent prior versions of XFractint SDL) in which an area of the image is only partially calculated. If I divide it up in to 6 horizontal strips, the first four and the sixth strip calculate fine. The 5th strip just sits there showing square blocks and never calculates them. Pressing Tab reports "Image completed".
Well, it's not so simple. Some small areas of the image (MultFace.gif) don't recalculate, yet other areas in the same rows of the image did.
I believe that changing to passes=1 will fix this. I have seen it before (initially with Xfractint years ago) and have a couple of example PARs that reproduce it. It has to do with the solid guessing routines and I would guess it is caused by the change from 16-bit integers to 32-bit (or 64-bit in this case) integers. Eventually, I'll look into it. The solid guessing routines seem like magic to me.
I switched it passes=1; still happened at the same places. passes=2 or 3 made it go away. Switching back to passes=g (after passes=2 or 3) made the entire lower third of the image render as large color blocks. Strange things, these computers! -- David W.
