We have a public facing website which is custom branded. Up until viewing the website in IE9 all standard Sharepoint functionality worked such as Site Actions.
All browsers work with it. Recently when we updated to IE9 the second level drop down has stopped working. I considered it to be a CSS related issue on our end, so I cleared the possibility of that by disabling it and it still didnt work.
I haven't managed to find a solution which works so wondered if anyone can shed a light on this problem.
