+- wxFrame can accept events, but apps cannot draw into it for
+ Workaround: use an embedded wxWindow.

+- The background of a window sometimes isn't restored when changing
+ notebook pages (see sashtest, mdi examples). The notebook background
+ colour shows through. A resize, or scroll, restores the correct
+ background colour.

+- samples/html/helpview and samples/help demonstrate that sometimes,
+ XPM images can't be loaded, perhaps only in 256-colour mode. This
+ will now cause an assert rather than an X error. But we need to
+ either cure the XPM loading problem, or provide alternative toolbar
+ buttons (for HelpView) and icons (for places where icons are used e.g.
+ in the log dialog).
