+\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}.
