Windows 7 64-bit With Adobe Reader/Acrobat?

I recently started having problems on two computers that both run Win 7 64-bit. The problem is that when opening a PDF file I get this box indicating to choose these options and then there is a check box to not ask me about it again. If I check it off, it goes away.Then when I try to close the tab that houses the PDF file, it will crash IE with acroread.dll being the culprit.What happens next is that if I try to read another PDF, the same box that I already told not to come up again will come back. It seems like it isn't getting the proper permissions to hold this setting. I found a fix via Google that said to just open up the Reader program and check off the box there -- that fixed the pop up box problem.The remaining problem is that gardless of if I update to the latest version of either program, I continue to have IE's tab crash whenever I close the tab that houses the PDF file.
