  • Tweaked layout code.

  • Fixed a bug where the use of tabbed MDI in a nested scenario within a parent document window could show the wrong documents in the active files menu.
  • Fixed a bug where nested DockSites could allow a tool window to close when its CanClose was false.
  • Fixed a bug where docking a ToolWindowContainer in inner-fill mode could sometimes cause its tool windows to disappear until the next arrange cycle.


  • Fixed a bug where the NavigationBar would change the SelectedPane property after the SelectionChanged event was fired instead of before..
  • Fixed issue with using default TextBox context menu in Breadcrumb control when in editing mode.


  • Added ability to set MiscCategoryTitle to null, which indicates uncategorized properties should not be put in a miscellaneous category.

  • Updated the SplitButton control so that Alt+Down will display its popup.
  • Updated the PopupButton and SplitButton to use commands for popup display. SplitButton.PopupCommand property added.
