Yes, I am having issues creating a panorama. The preview loads perfectly at 100% quality, but when I try to actually make the panorama, it fails because it "ran out of memory". Clearly this isn't the case since I have 128GB RAM, of which >120GB are free. It's happening because the core PhotoPad EXE is 32-bit rather than 64-bit. If I recall correctly, 32-bit EXEs can only utilize up to 2GB of physical RAM no matter what. I can confirm that this is the issue since the panorama fails when the quality is 30% or higher. Again, I cannot afford to lose ANY quality.
I am using 3 JPG files, the resolution of all three images is 6000x4000, the bit depth is 24, and they are each 300dpi.
