I am failing to find any way of stopping the Slideshow feature in Photo Gallery or File Explorer from cropping photos taken with my 3:2 picture ratio camera. It does not do it with my 4:3 camera. These photos are correctly shown with a black border at the sides. The 3:2 ones lose considerable top and bottom content and the feature is not useable with my 15 in laptop display with 1366x768 resolution, a ratio of 1.78. There are no settings anywhere to change this and this was not an issue with Vista or XP.
Has anybody else experienced this and can offer a solution please? I know I can use Powerpoint and other programs, but the built-in Windows feature was extremely useful for quick presentation preparation.
