RE: Possible problem with wchgat???

[Cy]

Well, I guess I can reply to this myself.

        "Leland, you're being stupid so shut up!"

It seems that wchgat only does a SetAttr (ORs the new attribs) and never
actually "touches" the window line, so the wrefresh() doesn't know it
needs to update anything.  Adding:

    wtouchln( wstat, 5, 1, TRUE );

Fixed the problem.

Sorry for the intrusion...
