We had the same problem here (on DPX2000 in SPIX32). The only solution
we have found is
the following correction in the code of vmh.c :

in the routine WINless: 
 
.........

#endif	notdef
		    lbottom = ltail;
		    while (waddstr (w, "~\n") != ERR)
			continue;
		}
		else {
		    wrefresh (w); 
		    return 0;
		}

	    if (!nwait)        <----------   suppress this line
		wrefresh (w);  <----------   suppress this line 
	}
