Hey Linc wondering if you have any other suggestions. I have tried all of the above but the result is that the pdf document doesn't even open in safari anymore -- all I get is a window with gibberish in it (see screenshot).
So, after disabling the Adobe plugins in the library folders, I can't manage to open any pdf's in Safari. The only way I can get the function back is to put the adobe plugins back into the library folders.
This has me stumped. I would really like to only use preview because of the scrolling problem.
Any help appreciated.
BTW Adobe itself suggests the same method of disabling Reader as the preferred app in Safari: http://helpx.adobe.com/acrobat/using/display-pdf-browser-acrobat-xi.html
Adobe also acknowledges, very unwillingly, that their scrolling in Safari is s***: http://forums.adobe.com/thread/1225213?start=40&tstart=0
