I put examples of my problem online at http://www.geobop.org/Test.php and http://www.geobop.org/Test2.php.
It was working fine until recently. I don't know if the problem was caused up upgrading to jQuery 1.3.1 or if I just messed up my files somehow. The scripts on the first page don't work at all. But if you mouseover the Microsoft banner in the top right corner, you'll see that something is happening internally. As I recall, I originally added the following CSS styles in the head section to fix a problem with #triggerRegions' menu (top center of the page)... <style type='text/css'> .trigger { position:relative; cursor:pointer; z-index:2; } .menu { position:absolute; visibility:hidden; overflow:hidden; z-index:1; margin:0; padding:4px; background:#BF8660; } </style> In the second example, I added the CSS styles again, but the scripts again don't work. However, if I delete the line "visiblity: hidden," then everything works perfectly - except that a little table listing regions is frozen open when you load or referesh the page. How can I fix it so that ALL my menus remain invisible until someone mouses over them? I had some suspicions that there might be some sort of conflict with one my style sheets, but I haven't tracked it down yet. Thanks for any tips.
