This is the biggest JOKE ever. It's bad enough there is a KNOWN bug forbidding users to scan over a certain size. Now that Panther is out, it won't work at all. SLOW download, the installation program is a joke. had to force quit the scaner finder. And since they were kind enough NOT to give an UN-INSTALLER, I had to do a search for date modified, and get rid of everything it dumped on my hard drive. Since buying this scanner, I've been SICK of booting classic every time I want to scan. I want my money back. I will NEVER EVER buy another Microtek product again.
