No dropdown menus in IE7
I am completely new to the templates aspect of Tikiwiki although I have been using the system for a while. I have just found the Tikipedia theme and love it. My problem is that the dropdown menus do not work in IE7 although they do in Firefox 3.0. Actually, other themes have the same problem too, so it's not a problem with Tikipedia.
If I look at this site (themes.tikiwiki.org) with IE7 and change to the Tikipedia theme, it works fine, but my own site http://www.ecwaevangel.org/living_in_nigeria does not.
I recently upgraded from 1.9 to 2.1 using the automated upgrade supplied by my hosting company, but I haven't had any problems other than this one.
Any simple answers, or suggestions as to where to start looking?
