Hello. In gx11.c, function buildLoginDialog, there is a call to: 1116 gtk_box_pack_start(GTK_BOX(vbox),hbox,TRUE,TRUE,0); followed a few lines later by: 1198 gtk_box_pack_start(GTK_BOX(vbox),hbox,FALSE,FALSE,0); with vbox & hbox the same values. The 2nd line generated a warning in the console: [ ERROR ] (Library::Gtk-CRITICAL) gtk_box_pack_start: assertion `child->parent == NULL' failed so i guess one is not exactly required :) Which one, now, i don't know, since i don't really master GTK.
