I have stumbled. Archlinux does almost everything to perfection, so I am concerned I may have erred in the installation of tuxguitar. I am uisng a 64 bit, a relatively mature installation with many packages installed, including many from AUR. Tux guitar works well, so far; however, when trying to access Documentation through "Help>Documentation" Tuxguitar hangs. I've spent some hours researching this problem, and have gotten nowhere. Every google search I make leads one to mention of SWT, and apparently the most up to date 4.2 version, and some issue regarding gtk. The following messages are received: (TuxGuitar:10351): GLib-GObject-WARNING **: cannot register existing type 'GtkWi dget' (TuxGuitar:10351): GLib-GObject-WARNING **: cannot add class private field to in valid type '<invalid>' (TuxGuitar:10351): GLib-GObject-WARNING **: cannot add private field to invalid (non-instantiatable) type '<invalid>' (TuxGuitar:10351): GLib-GObject-CRITICAL **: g_type_add_interface_static: assert ion 'G_TYPE_IS_INSTANTIATABLE (instance_type)' failed (TuxGuitar:10351): GLib-GObject-WARNING **: cannot register existing type 'GtkBu ildable' (TuxGuitar:10351): GLib-GObject-CRITICAL **: g_type_interface_add_prerequisite: assertion 'G_TYPE_IS_INTERFACE (interface_type)' failed (TuxGuitar:10351): GLib-CRITICAL **: g_once_init_leave: assertion 'result != 0' failed (TuxGuitar:10351): GLib-GObject-CRITICAL **: g_type_add_interface_static: assert ion 'G_TYPE_IS_INSTANTIATABLE (instance_type)' failed (TuxGuitar:10351): GLib-GObject-CRITICAL **: g_type_register_static: assertion ' parent_type > 0' failed (TuxGuitar:10351): GLib-GObject-WARNING **: cannot add private field to invalid (non-instantiatable) type '<invalid>' Also interesting, in the "About" screen, is the following information: This product include third party libraries: -> SWT (Standard Widget Toolkit): http://www.eclipse.org/swt/ -> iText (Free Java-PDF library): http://www.lowagie.com/iText/ The documentation is pretty good, in general, on the Archlinux Wiki. I could not find much useful information regarding this problem with Tuxguitar with respect to Archlinux, even there. Can someone shed some light, or, better still, suggest a way to solve this problem. I suppose I can try to get a PDF of the docs, and use that.
