Set preview as default PDF viewer

Hello,

I downloaded the update for Adobe Reader and during installation, it over-rode my choice to use Preview as my default PDF viewer in Safari. I've searched high and low and tried to change this from both Safari's preferences and Adobe Reader's preferences. Unfortunately, the section to "click" in Adobe is grayed out and will not allow me to deselect it. I also tried uninstalling Adobe Reader, but that just caused Safari to not open any PDF documents.

Any thoughts on how to correct this are greatly appreciated.

Many thanks,

Eden
