interaction with multiple windows works fine.
Sorry!

<pre wrap="">Puzzling and unfamiliar. Works fine for me on a MacBook with VPython
5.11, MacPython 2.6.2, OSX 10.5.7. There shouldn't be any difference

this area between VPython 5.1 and 5.11.
Could you please post a small test routine that fails for you? I
successfully ran the following:
from visual.graph import *
scene.x = 0
scene.y = 400
scene.range = 4
b = box()
y = gcurve(color=color.cyan)
pick = None
while 1:
rate(50)
if scene.mouse.events:
m = scene.mouse.getevent()
if m.drag:
dragpos = m.pickpos
pick = m.pick
elif m.drop:
pick = None
if pick:
newpos = scene.mouse.pos
if newpos != dragpos:
pick.pos += newpos-dragpos
dragpos = newpos
y.plot(pos=(newpos.x,newpos.y))
Independent of the graph issue, I did notice that on Windows I didn't
need the "rate(50)" but I did on the Mac, where otherwise dragging was
sluggish.

<pre wrap="">Hello,
I'm trying to develop an interactive application with two windows:
one
in which a user drags a sphere around; another which plots a graph
(using gdisplay and gcurve).
When I use only the display, I can drag the sphere around fine, using
code similar to the toroid_drag.py example. When I add the graph
display, my first window doesn't receive left mouse button events
anymore and the sphere doesn't move. The order of window creation
doesn't change anything.
How can I have two windows and interactivity? I'm using VPython 5.1,
MacPython 2.6.2, on OS X 10.5.7.
