+\wxheading{Win32 notes}
+
+wxTreeCtrl class uses the standard common treeview control under Win32
+implemented in the system library {\tt comctl32.dll}. Some versions of this
+library are known to have bugs with handling the tree control colours: the
+usual symptom is that the expanded items leave black (or otherwise incorrectly
+coloured) background behind them, especially for the controls using non
+default background colour. The recommended solution is to upgrade the {\tt comctl32.dll}
+to a newer version: see
+\urlref{http://www.microsoft.com/msdownload/ieplatform/ie/comctrlx86.asp}{http://www.microsoft.com/msdownload/ieplatform/ie/comctrlx86.asp}.

-\section{\class{wxTreeItemData}}\label{wxtreeitemdata}
-
-wxTreeItemData is some (arbitrary) user class associated with some item. The
-main advantage of having this class (compared to the old untyped interface) is
-that wxTreeItemData's are destroyed automatically by the tree and, as this
-class has virtual dtor, it means that the memory will be automatically
-freed. We don't just use wxObject instead of wxTreeItemData because
-the size of this class is critical: in any real application, each tree leaf
-will have wxTreeItemData associated with it and number of leaves may be
-quite big.
-
-Because the objects of this class are deleted by the tree, they should
-always be allocated on the heap.
