#1 Logged. Hopefully will get this fixed before release (it is a little annoying).

#2 Try this:

windowManager\win32\winDispatch.cpp

Change WM_SIZE handler to this:

case WM_SIZE: {
         if (window && wParam != SIZE_MINIMIZED && !Journal::IsPlaying())
         {
            window->resizeEvent.trigger(window->getDeviceId(), LOWORD(lParam),HIWORD(lParam));

            // Lock and unlock mouse to remove any mouse wackiness
            // This avoids issues with mouse being offset on resize, etc
            window->setMouseLocked( true );
            window->setMouseLocked( false );

         }
