     // WM_MOUSEMOVE instead of allowing it to blink normally.  To fix this, we

     // of passing them along.

     // has a selection that starts at the edge of the edit, and proceeds to the

     // edge of the text.  I think on each WM_MOUSEMOVE the edit is repainting its
     // previous state, then updating its internal variables to the new state but
     // not repainting.  To fix this, we allow one more WM_MOUSEMOVE through after
