Curtain problems

[keastman]

Hello,

I would like to temporarily make the screen blank. Previously, I used the "curtain" function with vizard 1.08, but know that doesn't seem to work. The new "visible" function in visard 2.0 doesn't seem to work either. When I put it in the command line. I get:

Traceback (most recent call last):
File "<string>", line 2, in ?
File "test3.py", line 7, in ?
viz.visible(viz.ON)
AttributeError: 'module' object has no attribute 'visible'

However, it does exist in the help and in the viz.py file.
