Editing & saving a unit property through Edit Unit not working

[Philippe SCHMUCK]

James,

When I try to modify a unit property through the button « Show Unit Properties », it seems that the change I make in the Unit Properties window is not saved.
Other strange thing : if I call the « Show Unit Properties » window and make no change at all, when closing the Edit Unit window using the Cancel button, a dialog show that the unit has some unsaved change even having modified nothing at all.
(changing the property using applescript works perfectly)

Thanks,
Philippe
