GOING CRAZY!! Cant keep menu centered!

this is driving me crazy, i can't seem to keep the dropdown menu centered where it should be when the resolution is changed.

it looks fine at 1280x1024 but just about every other resolution screws it up.... can someone please help me?

also, why is a horizontal scrollbar showing up on 800x600 resolution? my table width is set to 750 for cryin out loud.

by the way, the menu is a script i downloaded off dynamicdrive

Umm...why does your website reload every single time I resize the window?

i dont know.. i dont have any specific script for reloading the page

You might want to fix the reloading problem.
And about your question. I don't understand it...can you explain more?

take a look at the website in 1280x1024 resolution then change to 800x600 and you will see the problems =/. the menu bar gets off-centered and a scrollbar appears at the bottom of the page. about the reloading thing, i think that is part of the script for the menu so if people resize the page the menu refreshes to a new position.

ok now i see why you were confused. i am looking at the site in mozilla, but in internet explorer it isnt centered period. i'm assuming this is because of the scrollbar on the right. is there any way to fix this problem without removing the scroll bar?

if your using a layer then i dont think it will centre well, either put the entire site content inside one giant layer or have it absolute left
