I see a lot of gtk problems: Viewer, changing between Halftone and Lineart, and changing Halftone pattern in advanced options. Keeps running though. Gtk-CRITICAL **: file gtkbox.c: line 368 (gtk_box_pack_end): assertion `child != NULL' failed. Gtk-CRITICAL **: file gtkwidget.c: line 1427 (gtk_widget_show): assertion `widget != NULL' failed.

Gtk-WARNING **: invalid cast from (NULL) pointer to `GtkSpinButton' Gtk-CRITICAL **: file gtkspinbutton.c: line 1515 (gtk_spin_button_set_wrap): assertion `spin_button != NULL' failed.

Gtk-CRITICAL **: file gtkwidget.c: line 3310 (gtk_widget_set_sensitive): assertion `widget != NULL' failed. 2) Changing a few times between Halftone and Lineart makes the Brightness and Contrast sliders in the standard options window disappear permanently when set to Lineart (the autothreshold is still there). I have observed this with previous versions of xsane as well. 3) I have a huge conceptional problem with scanning 2-colour images and applying a threshold. There isn't anywhere to set a threshold value. The scanning itself would have to be done at grayscale of course. This seems a basic operation to me and I can't see why xsane doesn't seem to support it, considering many advanced features are there. The scanner supports grayscale. HP 4P sane-find-scanner: found SCSI processor "HP C1130A 3540" at device /dev/sg0 Thanks for a marvellous program!
