InfoViewer and MyDoggy issues

Using the MyDoggy dockable window manager breaks the InfoViewer dockable. The window itself will often remain invisible even when added to the taskbar, and closing it with the operating system rather than the window manager (by explicitly typing "wm.removeDockableWindow("infoviewer")") often causes the NPE that prevents jEdit from closing without doing a force quit. There are also no exceptions printed to the activity log.
