Drop down conflicting with profile

[Dyr]

simtrade.proboards.com

There's my test site above, where I have it set-up. Everything works fine until I get to my tabs menu.

I get the error message when I edit my profile that:
"We could not verify that you submitted the modify profile form from the correct location. Your browser may be having troubles storing cookie information properly. Please try again." However I know this is false because when I remove the code below, the profile modifies fine.

I also noticed, when this code is in, that when I try to modify my profile and get the error message, the url isn't the usual admin profile, but actually simtrade.proboards.com/index.cgi. I'm not sure if this will help anyone, but thought I should mention it. Did I make a mistake? I have it at the very bottom of my global headers, should it's position be moved? Any advice is lovely.

I'll take a look at it when I get home

I tried using this and it doesn't really do much other than display the following:

Home
Quick Links
Admin
Login/Switch Character
Logout

register
open threads land info user & char directory history & plot
staff intros contact admin

Just randomly on the page, what should it do so I can reproduce the error?

I was actually tweaking with it earlier, it's used on proboards and wouldn't let users modify their profile. I discovered it's because I had this in the css:
.ddcolortabs a span{
float:left;
display:block;
background: transparent url() no-repeat right top;
padding: 4px 8px 2px 7px;
}

and, since I wasn't using a background image, it was requesting information that wasn't there whenever a user modified their profile so it went in to error. So I just removed that part and just made the background transparent. All fixed now! Thank you for being able to take a look at it though. :]
