When using the menuButton Widget I found that the
menuName ressource does not seem to 'get' copied internally
so that if I don't re-allocate a string first all menu buttons
created in the same routine will call the same 
simpleMenu widget to be poped up (i,e the last one).
This seems to be a bug since all other widgets usually
copy  strings internally.

	char tmp[10];
	for(i=0;i<5) {
	n=0;
	sprintf(tmp,"m_n%d",i);
        XtSetArg(arg[n], XtNmenuName,tmp); n += 1;
	...
	create button menu widget
		}

when I replace this with tmp=malloc(10); then everything is ok.

Also:
	Is there an easy way to tell a viewport widget to
postion the top/left corner of the child at a desired position.
I need this because I have a (large) list widget child in which I would
always like the current item to be visible. It would be nice
to have the same way of positioning viewport thumbs as in the
scrollbar widget.

thanks
