HTML issue with web pages only shows up in Safari Options

[Chantal]

Hello! I am new to the group and very happy to have found you! I have used this forum for reference on other issues but I seem to need to come out of lurking mode for help on this one!!

I designed a site for a friend:

http://www.demfamilyarts.com/devzone/calendar.htm

This works fine in Firefox, Chrome and even IE (!!) but I hit a snag in Safari... for some reason my background image will not extend to the length of the page, it shows at the top but stops and gives me this big ugly white background instead.

Can you tell me what I am doing wrong? Anyone else had this problem before?

Thanks a bunch!
Chantal
