The WinLauncher utility isn't a true web browser; it's just a small
launcher application that wraps WebKit and allows simple testing that
rendering and other functions work properly.  Much of the
functionality you are hoping for is provided by the browser, and is
not implemented in WinLauncher.

No logic was included to launch new frames.  This might be controlled
by a preference, but I haven't looked into this as I did not need
separate windows for my program.

WebKit is executing the alert; it's just that the default
implementation is a no-op. You need to provide a delegate to do
something with the alert message.  This is provided by the
"runJavaScriptAlertPanelWithMessage" delegate method, defined by the
IWebFrameLoadDelegate interface.  Take a look in the "include/WebKit"
folder after a build is complete to see the declarations for this

I have not tried this functionality out.  I know some of the other
HTML5 test cases used to work, but I haven't looked at them recently.
