pages. Note that this won't disable the theme on the actual notebook background (noticeable only if there are no
pages).}
-\twocolitem{msw.staticbitmap.htclient}{If set to 1, allows the static bitmap to respond to mouse

+Setting this to 0 causes more flicker, but allows applications to paint graphics on the parent of a static box
+(the optimized refresh causes any such drawing to disappear).}
+\twocolitem{msw.display.directdraw}{If set to 1, use DirectDraw-based implementation of
