I am not sure how to describe this. Adobe cannot display information. often I get the window outline for adobe reader but it does not display the information in the window. It does funny things on the screen. Like if I touch areas some parts of the PDF will display. I have a powerful NVidia video card 9600 GT - 1GB memory. I have repaired Adobe Reader 9 and updated to latest releases.
I have a 6700 Quad Core with 8GB windows xp pro with 3gb switch on and dual monitors Samsung 213T 1600x1200 & ACERX263W 1920x1078. All my other programs seem to work fine. In fact Bluebeam, Paperport etc all display pdfs okay.
