	Hello,

	I don't know what scanning program you are using, but there is a bug in SANE 
1.0.17 where the first scan of a second frontend session (ie a previous was 
finished) would hang and fail.It is fixed in CVS by now. So I think it is 
worth testing with this version.

	By using LD_PRELOAD, you can force your favorite frontend to use 
a "hand-compiled" version without installing systerm-wide.

Regards,
	Stef
