As David implied, the fact that you changed the import statement (getting rid of the ugly "import *") has nothing to do with the fact that your script is executed successfully or not. This warning message is just about Python programming guidelines, that's all.
Now, I've tried to run this script as I have both VPython and Spyder installed, and the program runs smoothly, as many times as I want with both Spyder v2.1.10 and v2.2.0dev. In other words, I can't reproduce this bug. Note: for my tests, I ran the script in a dedicated interpreter. If you are trying to rerun the script again and again in the same interpreter, then it's normal that the interpreter quits after its first execution (it's related to VPython internals). Don't forget that VPython is tweaking IDLE to make some things work (I don't really know the details, I just remember seing a patch for IDLE in VPython installer).
