I'm having trouble with popup windows.  Under openwin and under
whatever DEC's window manager is (mwm?), I can't manage to type to the
popup.  I get perfectly fine behavior using twm.  I assume that a power
struggle of some sort is going on between my application and some window
managers.

My program is written using Xt and the old HP widgets, and I'm building
a popup window on the fly.  Here are some code fragments:

void
fname_popup(popup_pop)
    Widget popup_pop;
{
...
    i = 0;
    if (mono) init_mono(args, &i);
    XtSetArg(args[i], XtNx, x); i++;
    XtSetArg(args[i], XtNy, y); i++;
    fpopup = XtCreatePopupShell("FSavePopup",
        transientShellWidgetClass, popup_pop, args, i);
...
/*
 * Create the text widget to solicit the filename.
*/
    i = 0;
    if (mono) init_mono(args, &i);
    XtSetArg(args[i], XtNeditType, (int) XwtextEdit); i++;
    XtSetArg(args[i], XtNxRefName, (String) "FSaveText"); i++;
    XtSetArg(args[i], XtNxAddWidth, (Boolean) True); i++;
    ftext = XtCreateManagedWidget("FSaveName",
        XwtexteditWidgetClass, fform, args, i);
...
	XtPopup(fpopup, XtGrabExclusive);
}

I never have understood popups very well.  Can someone tell me what I
might do to resolve this problem?  I'm hoping for a solution that can
be implemented in a few lines, of course, using the HP or Athena
widgets; I'm not ready for a wholesale rewrite in another widget set.
