I have not been able to make the external view use photoshop for
opening up the tif files from vuescan (version 7.2.7) on a Macintosh
platform.
I have changed the information in the file exchange control panel to
indicate that photoshop should open a .tiff or .tif extension but the
icon still shows to be a quicktime icon and opens in quicktime picture
view.
I have always saved the cropped tif files from vuescan to disk and
then opened them with photoshop. I have never been able to get file
exchange to work. If I double clicked a .tif file it would open in
quicktime.
I am using system 9.1
Has anyone made it work.
