SOMETHING COVERING LINKS!, HELP! Options

[ZeT0]

Alright, right now I'm stuck.
Everything's good, and works find, expect some links up the top left.
They don't roll over, it's like something's on top of them stopping them from rolling.
Help me out?
EDIT :
Found my problem, it was my twitter, it was setting a mask so to speak over everything above it.
Preventing it from being click-able.
What can I do to stop this from happening?
EDIT :x2
Fixed my problem. :)

CODE

.twitter {position:absolute; top:1055px; left:50%; margin-left:-550px; _margin-left:px; width:290px; height:290px; z-index:4;}

The height was previously set to 1000.
Thanks anyway. :)
( I wasn't sure how to delete the whole thread. )
EDIT :x3
Okay, now this is making me angry.
It's at top:1055px; but that's WAY under estimated.
It should be around 2500, so for some reason the positioning is weird.
But according to it, 1055 is where it needs to be.
Where 1055 actually IS on the page, the links don't work.
It's still like it's covered.
Any ideas?

I was slowly fixing it myself. Failed, but the edits were necessary.
I finished this layout : http://www.myspace.com/californiarise
But I'll try and explain.
In my code, the twitter is set to be at top: 1055(ish).
When it SHOULD be at around 2500(ish).
Now where 1055 actual is on the layout ( in the header somewhere ).
It's like an invisible mask, not allowing you to click anything.
You'll see as you hover over the first individual band picture, it only works around the edges.
Depending on how far down/up I move the twitter, the 'masked' area moves too.
I moved it up further so it didn't block off the whole contact table.
I hope you understand all that.
Thankyou.
