I came up with a work around. I took the suckerfish menu out of the InternetGazette theme and incorporated it in my site (GlobalBiz theme) which seemed to be working fine until I opened the site in IE (versions 6 or 7).
In Firefox the mainmenu looks the way I want. In IE all of the menu items are stacked vertically. Any idea why this is?
this is a very big long shot but are you publishing the menu in a module position? if you are trying changing the parameters to either flat list or horizontal
i added that to my page on an internet gazette theme, and It did solve the issue with the menu but now the color scheme is broken. (The color scheme behind the menu items.) It is looking proper only on the button that displays showing the active selected page.
The change proposed earlier does fix the horizontality of the suckerfish menu, but somehow changed the color scheme. Now even when I changed it back to its original state, the color scheme is still broken. I wish I knew what I did wrong, but it appears that the change has effected the site on a permanent basis.
