Message tests calling SetFocus() on a button fail on my Windows 8 machine,
because they get a WM_CANCELMODE message they weren't expecting. I have no idea
what's special about my setup. It doesn't matter if I run the test stand-alone
or with the full test suite, or if I run it as a dedicated user with a default
configuration.
