I didn't actually tested it, but I saw a message on the forum of wxPropGrid...
about the wxScintilla, where is the newest version (for download, I don't have CVS)?
Because the first RC of wx2.8 will come next week (they say...), I want to test those libs, so when they work without problems they could be added in the SVN. That way it would be easier to switch to wx2.8.
