is the lag issue occurs with only one form*, some forms* or all forms ?
If * : are they simple forms (one page, a few fields) or complex forms (many pages, many fields with many calculations) ?
Actually, revently I have noticed that it is not just forms. Its all PDF documents. I ununstalled Acrobat X and tried just using Reader to preview the docs and same thing. I then uninstalled Reader 10 (or whtever the latest version is) and installed 9.4 and the problem still persists.
The mac is having no problems other than that, it runs like a dream. But this Reader problem is driving me crazy. I cant even scroll through a document because its just so laggy
Did you try to run Reader and/or Acrobat in 32 bits mode ?
(Right-clic the app icon : Show info : then tick the 32 bits checkbox)
Yes, I did. Then I ran it in 64 bit mode and same thing...
I can't help futhermore.
You should ask Adobe, may be there is a conflict with another software…
The solution to my problem with lagging Reader and Acrobat were solved by following the above link. The only difference was I was not able to exclude RightZoom app from Adobe, so instead of allow a/exlcude this one. I excluded all/only allow these. If you have RIghtZoom app installed on you MAC (regardless of the version of OS you're using) this fix work. After 9 months of fustrations, problem solved.
Holy crap. You have no idea how much youve helped, no **** but i love you. I was ready to call apple support.
