[sane-devel] [Fwd: Re: scanimage OK, but problems with xsane]

[Louis Lagendijk]

Hello Paul
I guess I reproduced the problem. I managed to reproduce the problem
when I opened the preview window in xsane. Scanning then fails. I
disabled the experimental button handling code, and it works for me now.
Could you please check the latest cvs code and report if it works?
Thanks for the bug report

Br, Louis
