I have a little problem with the usage of XmMessageBox of type WORKING.
I want to be able to pop up a WORKING dialog to inform the user that 
he will have to wait for a while. After the computation (or whatever) is
finished the dialog should automatically disappear (i.e. the program takes care
of the unmapping).

Example:

	PopupWorkingDialog("Saving file");
	SaveFile();
	PopdownWorkingDialog();

The problem is to get the dialog window is displayed properly.
I use the following code to get the dialog displayed in the routine 
"PopupWorkingDialog" :

	dialog = CreateWorkingDialog(...);
	< unmanage all buttons ... >
	XtManageChild(dialog); 
	while (XtAppPending(appcontext) != 0) {
		XtAppNextEvent(appcontext,&event);
		XtDispatchEvent(&event);
	}

With this code the window of the dialog is displayed but not the text in it !
If I turn the loop into a for-loop and loop 50 times everything in the dialog
window is displayed properly (but that is not a real solution).

What is the correct solution ? To handle some event that tells me when the
window is finished displayed by the server ?
I have also tried XPending abd XFlush with no success.

Many thanks in advance for any directions.
