I'm having a weird problem and hoping someone might have some insight, please

I'm designing a site with a shopping cart (using E-Junkie as the cart) and it also has some YouTube vids.

The shopping cart functions use Javascript. When I launch the site, the shopping cart window appears *under* my YouTube vids....which is kinda annoying

I tried using the typical "bring to front" under Objects > Arrange Objects, but this apparently doesn't affect Javascripts or YouTube.

Is there something I can do to make sure my shopping cart window is always at the front?

Any help would be greatly appreciated! Thanks!
