/**
 * SendKeysTest.cs: Test cases for SendKeys
 * 
 * These tests can only run in ms.net one at a time.
 * Since ms.net apparently hooks the keyboard to 
 * implement this, running two tests in a row
 * makes the second test run before the hook
 * of the first test is released, effectively
 * hanging the keyboard. CTRL-ALT-DEL releases
 * the keyboard, but the test still hangs.
 * Running each test separately works.
