Problem with Filmstrip style in IE7

[dragon300zx]

Ok I was made aware of a problem I am having last night and I have done some research on it and can't seem to figure it out.

First problem. My page width is set to 800px. How do I change that?

Here is the real problem though.

When using Filmstrip style in IE 7 some of my pictures will not show up.

The gallery is leecontracting.smugmug.com

When I click on pic #3 it will not show up. When I am scrolling through the photos using next it shows up but takes forever. Alot of the other photos will cause problems at time's too. When the images don't show up or when I click on #3 the box for the image appears, I get the thumbs drop down, but the image doesn't appear. I get an error on the page:

Line: 169
Char: 173
Error: Object Required
Code: 0
URL: http://leecontracting.smugmug.com/gallery/2828975

I have cleared the cache of temp inet files, cleared cookies as well. I have security set to medium and not high or med high.

Anyone have any other ideas?

I should add that the pictures are slow to load in FF but I do not get this error and the pics do eventually load.

In your css section delete this line: .Large #filmstrip (it's the last line)

For the width. If you are going to have the galllery style set to filmstrip try:
.gallery_2828975 #filmstrip {width: 960px !important;}
