whoa-this is weird…

Is the other wide screen computer using a different browser?
I’m using Firefox on a widescreen and I see the 2cnd level of your menu…
Anyway, just a guess here but you have a lot of list items in #menu which is nested in #header-wrap and then #header. #header-wrap has no assigned height. #header has an assigned height(216px)
#menu’s height is 3.0em which might not do the trick.Anytime you are setting a fixed height and the elements inside that are bigger than the height,things will disappear.

Test it out by adding overflow:auto to #menu. If a scrollbar pops up you have to make something have more height.
Try adding more height to #header or #menu or use height:auto…

ah, i’m pretty new at word press…where would i find this #menu to add the “overflwo”auto”?

to answer your question both browsers were IE

i sure appreciate any help on this. thank you.

HELP!!!! i changed the menu height to overflow:auto like you said and it messed up my whole header section and website!!! i put it back to 3.0em and it still doesn’t work. someone please help me!

I never said to remove 3.0em from #menu. I said to add overflow:auto to #menu. Just adding overflow:auto to a div with no height containing elements with height was not my advice. What I was suggesting was adding height to #header-wrap or #header,respectively.Adding overflow:auto to #menu was just to show you that 3.0em was not enough height for #menu.
In #menu each list item has a height of 48px yet the entire nested header structure only allows for a height of 48px which is about 3.0em. What’s going on is #menu is trying to incorrectly contain at least 96px of elements, #header and #headerwrap are doing nothing to help out and are being used to show background images when they should be being used to hold your blocks in place.
