I just installed the new driver software. thanks to tips in these comments I did a custom install. Smooth install.
I am so pleased. I can now easily scan items and then open the scan, as I wish into third party sofware (Omni Page PRO or Vue Scan).

For simple purposes, the direct Epson scan is alll I need.

And all this works in Panther! no need to use Classic.

Nice to see new life given to my several year old -but- in -good shape scaner.
