However, I would say this is at least worth a feature request. I don't see a real reason in putting numbers into the EXIF data of an image that do not reflect the real size of the image after the cropping process?

Furthermore, when I click on an image button to hide one of the images, a strange part of the complete image turns to black, so that I see less than what the 2 remaining images should amount to. This happens only when "Show control points" is checked. When it is unchecked, hiding an image behaves as expected. If I mask 2 images, than I see only a part of the remaining image. This looks a little like if the image masking used a Xor where it should use an Or. Hiding or revealing an image moves the 2 CPs, but there are always 2 CPs. The behaviour is not consistent: checking and unchecking "Show control points" when only image 2 is visible show 2 different results, both wrong, which come back in a 3 step cycle. Doing the same with image 1 shows 3 different results, all wrong, which also come back in a cycle. Doing the same with image 3 has the same pattern as with image 1. I added a 4th image to the panorama, but without generating new CPs, nothing changed and when this 4th image is dispalyed alone, I don't see anything strange in it's shape (but it shows completely white :-/ ) I am creating a bug in launchpad for this: https://bugs.launchpad.net/hugin/+bug/1258925 -- A list of frequently asked questions is available at: http://wiki.panotools.org/Hugin_FAQ --- You received this message because you are subscribed to the Google Groups "hugin and other free panoramic software" group.

As indicated in another thread here *Hugin 2013 problem with Fast preview on Intel HD 4600 (Windows 7) * https://groups.google.com/forum/#!topic/hugin-ptx/EC-DShQjDus three of us do not have problems loading images or aligning them on Win 7 64-bit but we do have problems with various parts of the fast preview.
