Kirk,
Build 3181 slideshow (with no transitions) worked for 2 new images and two that had hung before and then hung on one that had stalled before. Using the left-arrow key moved the hung image back twice, then the right arrow key moved the image forward once. but it hung entirely at that point. I closed slideshow, selected some more images, launched slideshow again, using new images, it worked for two images then hung, went back one using left-arrow key but this time slideshow hung completely. I closed slideshow, selected more images, different ones again, tried to launch slideshow but received a completely black screen, did this twice more with same results. Closed slideshow, launched again with different images and got the black screen with the white square in the upper left-hand corner of a black screen. I exited PM6+ entirely, re-launched it, chose 6 or 7 different images (with transitions this time), slideshow hung after displaying 3 images, exited slideshow. Re-launched and then got the black screen again. At that point I quit.
I didn't send any photos as you already have 4 of the ones that have hung before and I think you have the black screen one with the white square, etc. I had high hopes that the new build would work but there still appears to be a problem.
