 This item may fix a number of things.

 If you start wxnviz and display a map, close wxnviz, restart nviz...

 The 2nd time you start wxnnviz...

 id = self.nvizClass.LoadSurface(str(layer.name), None, None)

 in nviz_mapdisplay.py is not returning the id of the map. It returns only
 -1. It's got the name right in both cases. But it returns an id value the
 first time it is run, but not subsequently.

 This is at line 477 of nviz_mapdisp.py. I'm not sure, but it looks like a
 SWIG call in grass_nviz.py.

 Because this does not return an id value, a lot of other things begin to
 bomb.
