I am using Multi-Level Navigation Plugin v2.2.1 with WordPress 2.9
Menu works fine in Firefox but in IE8 when a dropdown menu appears from a parent link and then the mouse is moved to to a child link then moved off (without clicking the link) border and text of the dropdown menu doesn’t disappear. If the mouse is moved to another parent link the white border and text disappears.
I can’t immediately see any problems. You have some bizarre looking HTML in there. It looks like you have put the menu inside a table cell!?
I can figure out the problem, but I’ll need you to sign up for [iurl=https://geek.hellyer.kiwi/services/premium-support/]Premium Support[/iurl] first sorry, as it will likely be quite time consuming.
