IE issues - jquery Mega Drop Down Menu

Hi

I am trying to see why my jQuery Mega Drop Down Menu is giving me odd results in IE. I am calling the widget within the header portion within the Atahualpa theme (running WP 3.05 as we crashed when tried to upgrade to 3.1) hosted with HostPapa.com who provide the WP environment.

In Firefox/Chrome, etc., it is showing up properly as a horizontal menu with the appropriate call outs upon click through. Works.

With IE8, it is showing up as a vertical menu. Doesn't work.

Suspect there is some IF statement that I have to add if this is an IE browser, but not sure what code to put in (or where) nor the actual statement itself.

Site is www.swyc.ca

Any help is greatly appreciated as is all volunteer effort.

Thanks in advance,

James
