CSS issue between IE and Firefox - Floats

Issues with CSS displaying the same in IE and Firefox

[ChinoCharles]

Hello everyone. This is my first post. A little about me... my name is Charles and I just took my first web development job with a local newspaper publishing company. I have very limited experience with CSS and the like, but I'm getting better by the day. Shoot, I can still remember when Flash movies were cutting edge. Hah! I'm also a forum junkie so I suppose I'll spend a lot of time here. I'm a moderator <snip> Only natural I belonged to webmasterworld.com. ;)

A little about where I work... we operate 27 local news publications and all of the associated web sites. We program in Ruby on Rails. I wouldn't even want to think of what our directory tree would look like in PHP or some other language. RoR makes it a lot less cumbersome to navigate through our servers.

Anyway, the problem...

<snip>

At the first page, you'll see the login boxes at the top. On the second, you'll see the new look. We have a couple of drop down boxes, but the one next to the Search feature is the one of concern. If you're using IE, this box kicks to the right, which could pose a problem if the user is running a small resolution. If you're using Firefox, the hidden LI wants to wrap to the left side of the containing div. I'm at a loss as to how to handle this at this point. I've tried umpteen things and beaten Google to death.

Any help is appreciated... even a link to an existing thread. I tried searching but all of the threads in this forum seemingly have the same type of title, so I'm just going to post this and hope for the best.

I'm not going to post the code here just because there is so much of it. However, if you're using Firebug here are the applicable files...
dropmenu.css
dropmenu.js

Thanks in advance! I look forward to being an active member here and learning from you guys. :)

Welcome to WW!

Rule #1: Can't post links

[ChinoCharles]

Haha, really? My mistake... nothing I can do about it now. I guess it will be deleted and I'll resubmit without the links. :/

Mods, if you would be so kind as to not delete the post, but just edit the links out, I'd appreciate it.
