I've used IE6 to get to those without trouble. As I recall, the individual pictures in the gallery and the sections of the FAQ all use the same bit of code to open the items in a separate window (and as soon as you change the focus to a different window that original window closes) -- I looked over the code a few weeks ago out of curiosity. Do you have X-Mouse turned on in the Windows PowerToys (which would switch your focus back to the original window and immediately close the new window)?
