Certain Internet Explorer (IE) especially IE9 is having problem for drop down menu for some website (even sharepoint portal/website). Basically, the drop down menu is not working in IE9.
I have tried a couple of solution such as reset IE setting/configuration, enable compatibility view, etc but non is working. Finally, I solve it by disabled certain IE add-ons. Certain users that still have problem will need to start the IE without any add-ons.
Below is the screen capture to create shortcut on the user’s desktop that will start Internet Explorer (IE) without any add-on.
