Don't you need to filter the hiword and the loword from these?
Your setting the coordinates to the same long integer.
Just want to see if I'm right...

It is possible that CRichEditView::OnRButtonDown(nFlags, point); is
doing some default processing for you that is changing the state of the
cursor after you have changed it. Try either removing it placing it
before your code.

It seems like you shouldn't be calling the base class.  What happens if
you remove that call?
