[Edu-sig] LIVEWIRES Package problems...

I have never used the LIVEWIRES material, so I don't have specific 
knowledge. I was wondering if you are running this out of IDLE. The new 
version of IDLE (by default) does not merge the event-loops of Tk 
subprocesses. This leaves some graphics packages apparently unresponsive 
when being tested interactively under IDLE. If this is your situation, 
try running IDLE with the -n switch, or try using a plain vanilla Python 
shell (not IDLE) and see if that solves the problem.

If you are not using IDLE, then just ignore this post, as it clearly 
isn't your problem :-)
