Hi all, I have Adobe Reader for Mac v9.5.5 installed on my iMac (OS X Yosemite) and whenever I use it, for any sized document, it will lag as I scroll down or up in the document. The rest of my computer is fine and works like a dream. I want Adobe Reader to scroll in a fluid motion, like in Safari or in Preview. I use a Magic Trackpad with multi-touch gestures enabled, and to scroll I use two fingers using the inertia mode. Please help, thank you!
