[Visualpython-users] VPython 2.2 beta

[Bruce S. <ba...@an...>]

At http://cil.andrew.cmu.edu/projects/visual you can download the second 
beta version of Python 2.2 for Windows (2.2b2, also available at 
http://www.python.org) and a special test version of VPython for Python 
2.2. This test version of VPython has the new zoom convention set 
(scene.newzoom = 1), as will be the case for the regular version of VPython 
starting in mid-December, which is also the time frame for the release of 
the final version of Python 2.2. Zooming is done by depressing both left 
and right buttons on a Windows mouse. The new setting of newzoom has not 
been checked into CVS.

If you are just a bit adventuresome, we encourage you to try this out and 
report any problems. It is not necessary to uninstall the Python 2.1 
version. However, the desktop icon "IDLE for VPython" will be overwritten 
with one that points to the 2.2 version.

One thing to look for is that we think there may be a mouse problem over 
multiple runs, as though mouse status isn't being reset properly at the 
start of each run. A symptom could be for example that on a second run, 
moving the mouse with buttons up rotates the camera! We'd be grateful if 
someone could find and report a reproducible case of this to make it easier 
to test and fix.
