Comment 16 for bug 171579

Tests on Mac OS X 10.5.8 (i386) ok with
 0.48+devel r10764 Gtk+/X11 2.24.4
 0.48+devel r10764 Gtk+/Quartz 2.24.8 (menubar integration backed out)

- not registered as open: non-dockable dialogs
("older" dialogs like Text & Fonts, XML Editor, Tiled Clones, Object Properties, etc -> see bug #592323 and related reports mentioned in the comments there)

- not registered as open: minimized docked dialogs
(I make frequent use of this feature, with settings changed to only show the dialog icon, see screenshot attached to bug #648174)
Possibly GDL has hooks for saving dock-specific dialog states (open, minimized, detached)?

- I haven't yet fully figured out what happens when working with multiple document windows opened from within the same Inkscape instance: occasionally it seemed to me that the dialog states of the last closed window got added to the list of dialogs which had been open in the initial window (closed earlier), instead of replacing the states.
(Caveat: with current trunk, beware of the regression (crash) reported in bug #869067)
