When I open an image in Windows Photo Gallery it is squished over to the left and side of the screen. The image is also in black & white with vertical lines going through it. I was having the same problem when I made youtube and other flash movies full screen. I found a fix for the youtube problem but I can't find a solution for Windows Photo Gallery. Can anyone help?
To fix the flash player problem you should right click on the movie. Select 'settings' then click the monitor icon in the bottom left corner of the box. Uncheck 'enable hardware acceleration'. That fixed it for me.
I still haven't found a fix for the Photo Gallery problem.
