In printconf-gui-0.2.1, when you click new to create a new printer and then select Printer Driver, the list of choices starts with the scrollbar all the way at the bottom. Although there is certainly nothing wrong with this, it seems a bit odd as it is certainly more customary (and expected) for a scrolled list to start at the top. It would be better to start at the top anyway so that the user will see Text/PostScript/Raw at the top.
This was annoying, and caused by the author (Me) not being very experienced with gtk. You cannot do a 'moveto' call on a node in a ctree if that ctree is not exposed. (if you cared). This is fixed in latest. Try them at: http://people.redhat.com/crutcher/printing/
