Hi out there.

I traced the XmLabel redisplay problem and found out that my program
was crashing when I was doing :
	XtSetArg(arg[0], XmNlabelString, xmstr);
	XtSetValues(labelWidget, arg, 1);

For some reason it was crashing when _XmStringFree was called in the
Label SetValues procedure.

So this is how I got around it, although I shouldn't be doing this, especially
line 1:

XmLabelWidgetClass     	superclass = (XmLabelWidgetClass)xmLabelWidgetClass;
Widget			labelWidget;
XmString		xmstr;

... stuff deleted 

1: ((XmLabelWidget)labelWidget)->label._label = _XmStringCreate(xmstr);
2: XClearWindow(XtDisplay(labelWidget),XtWindow(labelWidget),0,0,
		    (int)XtWidth(labelWidget),(int)XtHeight(labelWidget));
3: (*superclass->core_class.expose)(labelWidget);
4: XmStringFree(xmstr);

The program doesn't break anymore !
Does anybody know why ?
