+// FIXME: A lot of mouse-related tests sporadically fail in wxGTK. This happens
+//        almost all the time but sometimes the tests do pass and the failure
+//        doesn't happen when debugging so this looks like some kind of event
+//        dispatching/simulating problem rather than a real problem in wxGrid.
+//
+//        Just disable these tests for now but it would be really great to
+//        really fix the problem.
