I've used Thomas Kahn's Smooth Div Scroll to make a photo slideshow on my site. The scroller works totally fine, except that it hides submenus that should appear when I hover over items in the spry menu bar. I thought this would have something to do with the z-index of the scroller, but I tried playing with that (and the z-index of the menu bar) to no avail. I'm a co-op student making this site for my employer, and we weren't taught how to do this kind of stuff in school so I'm a little overwhelmed. Any help is appreciated!

Here's the page I'm working on - http://jennymartindesign.com/Pages/portfolio_com.html

Here is the code for the page.

1) Padding is only placed on the top and/or bottom of the div. The elements within this div have padding on their sides. This saves you from any "box model math".

You may also choose to remove the padding on the element in the div and place a second div within it with no width and the padding necessary for your design.
