Hi, When I view a pdf document with kghostview and scroll back and forth the text disapears from view. The portion of the page that scrolled off the screen disappears and is replaced with a plain white background when I scroll back to it. Why is this happening? How can I rectify this problem? Which other free pdf viewers can I try? I am using debian woody. kghostview 0.12 kde 2.2.2 Thanks
