There was a similar issue a few years ago with Win7. I believe Brian
Paul fixed this by modifying the framework to enforce a minimum window
size depending on the operating system. It's better to fix this issue
once for all tests than change each individual test. This is especially
true since we may add more tests with too-small window sizes (since
we're not on Windows).
Brian, does that sound right?
