CS6 Mountain Lion PDF issue

Hi all,

I am running CS6 on my MAC Pro OS Mountain Lion. When trying to open a multi page PDF in illustrator I often do not get the page selection pop up and it automatically opens the first page of the PDF in illustrator. It is very hit and miss which PDF's will offer me the option to select the page to open and which will not, as some work just fine but equally some will only open the first page.

Is anybod else finding this an issue?

Thanks
