My Acrobat when I open it up and try to scroll down a document - freezes. I have to wait for it to unfreeze to carry on. I have uninstalled it, installed it again but its the same. I am not running a low end computer, there is enough memory and space, its very frustrating. I even pay for the low end subscription just to get some sort of editing functions - but this freezing up, slows down my work pace.
