Re: [Visualpython-users] Backwards-compatibility problems in Visual 5

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

See the documentation on displays, where you'll see that you can indeed 
change the title and other properties of a window, but you must make the 
window invisible first, then make it visible again. The rules in Visual 
3 for changing window properties were somewhat vague and inconsistent.

In the "What's new in Visual 5" you'll see listed as a known bug that 
scene.cursor isn't yet available.

I wasn't aware of a change from list to tuple for scene.objects, but 
clearly it ought to be a tuple, not a list, as this should not be a 
modifiable sequence. In what context did it matter that it was a list 
rather than a tuple?
