I don't know if anyone has posted this before... When somebody post large photos in one of the topic threads the Subcommittee banner is displayed and you must go to the bottom of the screen list in order to have the scroll bar to see all the text and photos (slide left to right).
When that happens, I go back to the topic entry again and right click and select open in new window. That eliminates the Subcommittee banner and the full text and photos are displayed with nothing cut off.
Could you either put up a notice to do the right click and select open in new window, or modify your web program to open a new window automatically when someone exceeds the normal screen width in the topic thread?
I've seen this problem in Jeff's U-Boat Pen in the Type VIIC section.... I am running Windows XP SP2 IE7 and have a 20 inch flat screen display.
