IE6 elements out of place until mouseover?

Working on http://churchbcc.org.s14623.gridserver.com/

When I load the site in IE6, some text and image elements appear to
the left of where they should be. When I mouse over the element, it
snaps to the correct spot. If I clear the browser cache, the page
loads correctly. But when I re-load the page or browse to another
page, the problem repeats. Sometimes, the elements don't appear at
all.

The html validates, and everything is fine in Firefox, IE7, etc.

What am I missing here?
