[Visualpython-users] Problems on Vista

[Bruce S. <Bru...@nc...>]

It has been discovered that there's a serious problem in the beta 
version with the label object on Windows Vista. The first label object 
that is encountered, the screen freezes while the cpu runs flat out for 
about 30 seconds doing I don't know what. Then the label (and all other 
labels) display normally.

I have no idea what the cause of this bizarre behavior is, nor what 
level of the multitiered system is at fault (Vista, OpenGL, gtk, gtkmm, 
Visual....).

I'm in the process of reconfiguring an XP machine to run Vista so that I 
can work on this problem.

I've always had trouble with the Label on an XP machine. I have never seen a 
Label in VPython. Usually results in a GPF. Simple code that reproduces the 
problem.

from visual import *
a = Label()

That's very unusual. I've never seen that, on a very large number of XP 
machines, nor to my knowledge has anyone else reported this. Is your 
graphics driver up to date?

I'm sorry. I'm slightly in error. This is the minimal code that produces the 
problem.

from visual import *
label(text='hello')

Note that if i leave out the text parameter it works fine. all the other 
parameters work okay.
Also I get the gpf whenever a vpython tries to make a graph. I suspect it is 
related to text there also.

The mod name for the gpf is atioglxx.dll which leads me to believe it might 
be out of date. i will check around.

You are correct that if a simple label fails, graphs will also fail, 
since the labels on the axes are made using the label object.
