Error using setMask()

Hello all.

I was wondering if anyone might know offhand why the images at this link: http://brekkbockrath.com/design 2/lookandfeel2.html don’t load properly the first time. Because after you let the browser load all of the images, then refresh the page, they load perfectly.

I realize that I should be posting the source code, but I don’t have it right now. I will post it later today, for anyone interested.

Thanks for your time.
