I use Blender 2.61 and it doesn't work! It's a kind of funny... I can remember 20 years ago I could write: print "hello world" ... on the C64 and it put out a text "hello world"... but now 20 years later you have to set a lot of things in a 2*1024*1024 byte file just to put out a dynamic text like "blender"... and it still doesn't work in none of the prior versions of blender. For me, that's the evolution of incompetence throughout the line. The realization of the peter-principle!

Its work thanks
