New Revision: 16727

URL: http://svn.gna.org/viewcvs/relax?rev=16727&view=rev
Log:
The user function wizard pages now have an on_back() method which unregisters 
the observer.

This is needed as going back previously did not unregister the observer the 
object, hence going
forwards after going back would fail.
