hi
tested in IE9, no issue by my side

Thanks Ced - steps to reproduce.

Choose menu option: Specials Sale -> Catalogue OZtrail -> Sale Catalogue so the PDF viewer displays.

Then select menu again and it is hidden behind PDF object.

Thanks and regards
Brett

Ced - any update on this issue? Did you try my "steps to reproduce" yet?

Thanks
Brett

ok
have you tried to give z-index:10;position:relative; to the menu container and z-index:9;position:relative; to the pdf container ?

Thanks Ced - I will now contact the PDF object developer to work out how to put the Z-index in on their plug-in. Will let you know the results.

Best regards
Brett
