Firefox and IE Oddities

Hey Gang,

If you take a look at the site in IE, you will see a blue gradient under the navigation. This is how it's supposed to look. However you will notice 2 things:

1. There is a 1px jog between the blue gradient and the footer.
2. If you look at the sidebar to the right, you can see that the background image is repeated once too often. This doesn't appear in any other browser on the Windows platform. (Not too sure about Mac browsers yet, haven't gotten that far.)

Now let's take a look at the site in FF.

Everything is copacetic, with the exception of the blue gradient. It's not showing up, and this happens in nn 7.1 as well.

Any ideas how to fix this? These are the last 2 items that I need to squash before I can finally say the site is done.

Thanks a bunch,

Justin
