This is a bit a patch... unforseen issue with the new Screen Handlers.
(Screen handler is used now to trigger animated screen).

When files get saved with Verse_Blender, it has the verse handler set,
which causes the handler system to run without a means to disable it with
release versions of Blender. This patch disables the Verse Handler to be
set on reading files.

Jiri; you will have to uncomment this code when you sync it with your tree!
