Reader scrolling is laggy and choppy

Jul 3, 2013 8:14 AM

Reader scrolling is laggy and choppy in Mac (OS 10.7.5) to the point it is so slow and unpleasant that I avoid it at all costs. How can I fix this?

Preview refuses to search many pdfs; so I keep both apps open -- Preview to read, Adobe to search. It's very slow and unproductive.

I see an earlier post (2011) that mentions a possible contlict with an app called RightZoom, which I don't have; nor do I understand the solution posted for people without RightZoom (how do I log into a program I haven't installed?).

I'm not a techinical person, so need a clearly explained solution, if there is one. Thank you.

    How big are the PDFs that lag?

    Odd. I know for a fact that RightZoom will have no effect on this, since it is only a UI mod for maximizing windows with the green button. Besides, you don't have it installed.

    There's an app called "AppZapper". It completely removes an app and all associated files (preferences, plugins and .plist files)


    Download it, Install it, and open it.

    Drag the Reader app to the window and "Zap it".

    Empty your trash and then download and reinstall the offline installer.

    Then open a PDF the was lagging. Let me know if it persists.
