Since upgrading to Acrobat 7, PDF files will not open within IE6. I can view the PDF pages as they download but once they all finish, the whole window goes blank. If, in the Acrobat Edit Preferences Internet, I deselect the "Display PDF in Browser", then the PDF will open up, but it is then in Acrobat 7, not in the browser. I've gone through all the suggestions posted on Adobes web site in documents 328233 and 331025 but so far nothing has restored the plug-in ability.
