Re: [Visualpython-users] Editing label example... Doesn't

[Bruce S. <Bru...@nc...>]

This is a serious bug, previously unnoticed (I guess because none of the 
example programs use keyboard input). Thanks much for reporting it. 
Apparently scene.kb.keys is not getting set when there's an event. This 
bug is present in the latest 4.beta11 as well.
