FYI, in IE8, if I have a digital point ad with the "dp_ad_notice" option enabled on an Xenforo site, the digital point drop down notice interferes with other the "log in or sign up" links on the page. Once the digital point drop down ad notice disappears or is closed, the "log in" link no longer functions, I assume because the log in link also function as a drop down function. Also, this jquery error appears, which seems to be part of the Xenforo installation, but this message doesn't appear unless the digital point ad drop down appears first. Message: Invalid argument. Line: 156 Char: 295 Code: 0 URI: http://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js Code (markup): When I refresh the page, the problem doesn't exit.
Hmmmm... looks like you stumbled upon a jQuery bug. I changed it to not use that specific jQuery easing, and it seems the error goes away. Flush your cache and and it should be okay. In the meantime, I'm building a simple example so I can file a bug report with jQuery.
