 // This test launches chrome frame in full tab mode in IE by having IE navigate
 // to cf:about:blank. It then looks for the chrome renderer window and posts
 // the WM_RBUTTONDOWN/WM_RBUTTONUP messages to it, which bring up the context
 // menu. This is followed by keyboard messages sent via SendInput to select
 // the About chrome frame menu option, which would then bring up a new window
 // with the chrome revision. The test finally checks for success by comparing
 // the URL of the window being opened with cf:about:version, which indicates
 // that the operation succeeded.
