admin or user … tricky question. both? neither… It is run as service using the LocalSystem account. Probably closer to admin than user. I guess I could change the service to run under the users account and re-run the tests, but I wouldn’t run it that way in production just becasue it would lead to more mainenance when the user accounts change.
On the other point, I open and close the ds several times in a session, but I havent seem the problem you’re describing yet. I ran somewhat heavy testing a few months back and our epson did ok. I’m not an epson fan cause their twain implementation is … .. well, I think they could have done a better job, but for the capabilites that they do support, they seem to be consistant.
