alice-teacher Alice 2 - Possible Bug in Alice built-in Tutorial 4 (lunar lander)

At this time, there is no plan in place to fix this bug… The tutorials were created as part of a graduate student research project, and this bug has been in the tutorial since 2005. This is a bug in the tutorial framework itself. It is not a bug in Alice, or as the result of being used on any particular platform or operating system.

It is actually only in the last year that we have started to receive reports of this bug with any frequency, (which is somewhat curious, but another topic), and because there is a relatively trivial work around, it has not been high on our priority list. But with the number of reports we have been receiving in this past year, it is a topic we will revisit.

All the best,
Don Slater
