[vtkusers] Problem with picking on windows?

[David Duke]

I've been having a problem using picking via the pick operation provided 
by vtkRenderWindowInteractor.  I'm running 4.1.1, the nightly release 
from April 23.

Attached is a small Tcl script that illustrates the problem.  It sets up 
a white sphere in a window with an interactor, and when the pick event 
is completed, it is supposed to position a small red sphere at the 
selected point.

Under Linux (Redhat 7.2), this works absolutely fine.
Under Windows (XP), nothing happens on the 'p' key press.

I may be missing something obvious, but I'd be grateful if someone could 
have a look at the script and either see if they can reproduce the 
problem or let me know what I've overlooked.

	thanks,
	David
