r14724 - /1.3/gui/relax_prompt.py -- September 21, 2011 - 11:29

Author: bugman
Date: Wed Sep 21 11:29:31 2011
New Revision: 14724

URL: http://svn.gna.org/viewcvs/relax?rev=14724&view=rev
Log:
The GUI prompt window is now also deactivated with the execution lock.

This will prevent race conditions as previously the user was able to execute 
any user function or
manipulate any of the data in the relax data store, while execution was in 
progress!
