Not directly a bug, but an annoyance to Windows Internet Explorer users.
The "click to activate and use this control" has been resolved, this was an issue that started happening because of a lost legal battle between Microsoft and Eolas in regards to Active X components. Both the Navigation bar at the top, and the Submitted flashes should play properly at this point.
The fix implemented, as well as other sections of the site, use javascript, so if you have Javascript disabled, the site may not function properly.
I am still working on additional issues with the portal system, please be sure to report anything that you see that hasn't already been reported. Click here to view the current known issues.
