Dropdown menu margin issues with IE5.5/win?

I've got a fairly standard horizontal menu setup. Using MIR (malarky image replacement) on the root elements and each root element is one menu deep (no submenus).

The  problem is extra margin-left padding on the dropdowns. No matter how I fuss with the CSS I can't seem to make IE5.5/win step into line. It's about 1em (with a body{ font-size: .8em }) too much on the left. Not having the webdev extension available in IE is making it hard to tack down the cause.

I've looked through a couple pages on the forum but haven't seen anybody with a problem like this. Any ideas?

I'm not so much concerned about screen readers (although it's nice for crawlers) but more configurability. This particular site adjusts its layout depending on available browser width. So on small screens (pda, cell phone) it displays simple major text links but on larger displays the root items turn into images. Tricky.

Still fighting the IE5.5/win bug. I'll post if I figure it out.

Thanks for the reply, Angus.

Small update:

Using a conditional comment for IE5 ( <!--[if lt IE 6]> ) I set a rule for

.menulist  ul li {
  left: -1em;
}

which shoves the li in place. The menus are still not following my preset width rules and no amount of rules I throw at it are making a difference. It's as if the links have a white-space: nowrap; but I've even set white-space: normal; and they still don't listen. Jerks.

This makes me think that the width/no wraps are coming from something in the JS. I'll look into it later this week and will hopefully have an answer
