You mean the items that say, "Holidays, Cruises, Destinations..."? They do not work for me either with SeaMonkey or Firefox. They do work with Safari. The top image on the page does not indicate that it is part of a slide show, either, which it does with Safari.

No problem here to open those menus with a left mouse click.

You can try these steps in case of issues with web pages:

You can reload web page(s) and bypass the cache to refresh possibly outdated or corrupted files.

• Hold down the Shift key and left-click the Reload button
• Press "Ctrl + F5" or press "Ctrl + Shift + R" (Windows,Linux)
• Press "Command + Shift + R" (Mac)

Clear the cache and remove cookies only from websites that cause problems.

"Clear the Cache":

• Firefox/Tools > Options > Advanced > Network > Cached Web Content: "Clear Now"

"Remove Cookies" from sites causing problems:

• Firefox/Tools > Options > Privacy > "Use custom settings for history" > Cookies: "Show Cookies"

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.

• Switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance
• Do NOT click the Reset button on the Safe Mode start window

In my case, it is not an extension or theme causing that, nor is it leftovers from the cache or cookies. I did not allow that site to set any cookies, and I wipe my cache after each browsing session.

I think it is more likely some of the 88 errors reported in the validation check.

Me too. Tried Ctr+F5 and dropdown menu works but only once then at next attempt won't work. Also cleared cache with same result.
