I used to be able to use Reader with no issues but suddenly only the basic text is viewable--Title blocks, big fonts, etc are hidden in solid black rectangles--other computers display these pages fine. Not sure if this began before or after I updated to version 9--but I cant download version 8 to see if this is the problem. Support refered me here for answers but II posted a few days ago but my questions was ignored. Please advise. Thx.
