Thanks Alan, other desktops allow correct operation. Only Unity 3D has the fault, Unity-2D works fine. I had not considered that the desktop could be the problem. I hope to find the offending file or setting in the Unity configuration, as I would prefer to know how to fix this if I need to in the future. A clean install and restore isn't an option because my backup also has the offending error :( I have narrowed it down to 1 machine, so a little detective work should identify the offending file. ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
Re: [Tutor] Identifying V3 examples
The one example I specifically remember was this one http://code.activestate.com/recipes/532908-text-to-pdf-converter-rewrite/ - I happened to be looking for a simple pdf utility and this one was well reviewed. I subsequently have been told that the parts that 2to3 had trouble with were bad practice to begin with - but what do I know. Most of the other examples 2to3 converted (once I discovered it existed and how to use it in my setup) or I was able to decipher myself. I’ll take a look at your tutorial - thanks.

Problem solved. Unity settings are stored using GConf. Resetting Unity with the following: dconf reset -f /org/compiz/ then log out and back in.
