I have fixed this in CVS now. Please test in every mode. > I thought I had code in there for must_buffer, Yes, but it was more complicated because the 16 bit modes didn't work at all in must_buffer mode. See CVS. I removed support for the 16 bit three-pass modes which didn't work anyway. And three-pass scanners that support 16 bit won't be too common :-) hand-scanner mode with 16 bit should work, however. > but you are definitelya correct about the odd amount of data issue. > I wouldn't think the latter case could happen with a local scanner, > but with a network scanner I can see it happening.a A backend can define it's buffer size to e.g. 15 bytes. Or read can return an odd nu,ber of bytes. It can happen any time. I think I found a solution for this in CVS. Please test. Bye, Henning
