Several solutions are available:
1) The Motif shell widgets ASSUME that mwm is being used.  Using
   another window manager, while permissible, results in depreciated
   functionality.  For example, picture how things would look if uwm
   were used.  Therefore, the simpliest solution is to use mwm.
2) Set the dialog shell's XmNtransient resource to FALSE.  This will
   break the iconification code (i.e. a single icon for multiple
   windows) but should fix your title problem.
3) Use XtCreatePopupShell to create instances of
   topLevelShellWidgetClass rather than using Motif's convenience
   functions.  This is a better way to implement option (2).  It has
   also been tested so it's known to work.
