The above is not to say that Acrobat 8 will not run on Windows 7, but Adobe does not support nor did Adobe update version 8 to work on Windows 7. So there are a number of features that might not work or work sporadically.

drag/drop one or more TIFFs to an Acrobat window

also this way: from file menu 'open' (files of type 'all') or 'create pdf > from file' (files of type 'tiff')

Thanks. I was afraid it'd turn out to be an OS compatibility issue. The suggestion to drag and drop into an Acrobat window works like a charm, though, and ought to work until we decide to upgrade. Much appreciated!
