The issue we are having is that the Import PDF... command is not working, as described above, on one of our stations only. It is a iMac, system 10.5, with a slightly modified 'Architect' workspace. This station has the same plugins as the other machines in the office, and it does not have any Acrobat software on it. It does, however have 2 accounts, and we are going to look into seeing if this is causing any conflicts.
I did try to add the command in the workspace editor last night, as described above, but that does not accomplish anything. The Import Image File... does work. I even took my working plugins and put them on the unworking station, to no avail. The plugins we have are 'Export PDF (Batch)'; PDFPage'and 'PDFUtilityLib'.
Very odd behavior...
