alice-teacher Possible Issue with Alice 2.2 (12-1-2011 release)

[Lance Allen]

The student presses the PLAY button on the Alice IDE. After the animation
ends the student presses the STOP button. This takes her back to the IDE.
If she presses the PLAY button again Alice throws an error and the PLAY
button on the IDE is dimmed.

Here is an excerpt from the large error msg:

Alice version: 2.2  12/01/2011





*****Running World*****

*****Stopping World*****

*****Running World*****
