Epson's TWAIN 5.75A driver for OS X would not install on my machine (permissions failure at end of installation process). Is that because I am at 10.2.6? Also, were TWAIN 5.75A to nstall correctly, would Image Capture then be made aware of the film-scanner attachment of the 1660? Image Capture actually worked for reflective document scans but did not have a way to turn on the lid light of the slide/film scan attachment.
