	I need some help with the Ulowell C++ bindings for Motif.

My problem is that I can not pass a object (XMObject) as a argument
to a function that is in another source file.

	here is a short fragment of what I'm trying to do

----- main.cc
.
void CreateMainMenu( XMForm *  );  
// I've also tried, void CreateMainMenu( XMObject *  );  

void main (unsigned int argc,  char **argv) 
{
  XMApplicationShell topLevel ("topLevel", &argc, argv );
  XMForm mainWindow (&topLevel, "mainWindow" );
  CreateMainMenu( &mainWindow );
}

----- menus.cc

void
CreateMainMenu( XMForm * parent )
{
  XMString string ( "test" );
  XMLabel label ( parent, "label", &string );
  label.Manage();
}

The mainWindow is displayed but I get a message "Destroying Widget ..",
and the  label is never displayed

If I move the three lines from CreateMainMenu to main.cc and replace "parent"
with "&mainWindow", it works fine.

GDB show main.cc:&mainWindow and Menus.cc:parent to be the same address
and type.

Any help would be great

Config:
Sun 3 OS 4.1.1
g++-1.39.1
gdb 3.5


PS: I'd love to hear from anyone else who is using / trying to use
these bindings.
