Hi,

I can not seem to get my WIN_CONSUME_EVENTS to direct LOC_DRAG and/or
WIN_MOUSE_BUTTONS events to me!  LOC_MOVE seems to work fine, but
I don't get ANY events with any button down.  Can anyone help?  I
have included my xv_create() for the canvas below.  Is there something
I need to enable on the Base Frame?  If so what?
