Two computers - one computer uses IE7, the other uses IE6 When I click on a
web link to a PDF file I get different results:

On the IE7 computer, the PDF opens normally in Adobe Acrobat 81.

But on the IE6 computer, we first get a dialog box asking if we'd like
to open or save the file. Clicking on Open causes it to do just that.

I assumed the difference had something to do with my security settings. But
a quick comparison doesn't reveal anything obvious.

Please advise.
