I have a pdf file that was created by Page Manager version 7.15.35. I am unable to open this pdf when using Reader X; Reader opens but I get a blank dialog; no error message is produced. I tried turning off Protected Mode bu that made no difference. If I uninstall Reader X and install Reader 9.3 then I am able to open the pdf successfully. I am able to open other pdfs using Reader X. My only problem is with a pdf created by Page Manager 7.15.35.
