IE PC 6 users, check this site.

Question

I just checked the site below and the QuickTime movies smear across the entire site when you scroll. Does it do the same on your system? (If you were curious as to what a QuickTime movie looks like when it's smearing across the page, this is it. And it's quite ugly. )

Just one more reason to scare off IE users. I'm also curious as to whether or not it looks fine with IE 7.

Kyn,
Theoretically, using a jpg instead of a png should prevent the problem, BUT I think that iWeb will automatically change the jpg to a png when publishing, in which case the problem would remain. You can still use a png image as the page background, but do it following these instructions (step 1 is the most important one):
In iWeb, in each of your pages with the QuickTime controller,
1) go to the "Page" heading in the Inspector window and under "Page Background" select "None" (The Browser Background can have a color fill without affecting this issue.)
2) on the main iWeb window at the bottom, click "Shapes" and select the square
3) drag the newly created square all the way up the page, without yet resizing it, so that it is within the "header" section of the page (where the navigation menu is)
4) now leave it there and move the pointer back down to the bottom of the page and click "Backward" until the square shape is behind all of the menu text
5) now drag one of the corners of the square to resize it OR use the inspector pane (click on the ruler icon to get the "Metrics" pane) to resize and position it so that it spans the entire page.
6) again using the inspector, select the "Graphic" pane, and choose the fill type (color fill, gradient fill, etc.) for this new background. In the stroke section, select none, unless you want a border around the page background.
7) publish.
