We will try to get a release out with this fix ASAP...

But you might go back to he earlier release, which did not seem to have this problem...

You can still download and try the experimental version as most of the previous features will still work. All additional feature like the Spanish translation or the update menu is still work-in-progress. Download at http://www.cs.purdue.edu/homes/aik_min/. Let me know if you find any other bugs.

For Chapter 5, the “Zeus” exercise worked through in the chapter, we’re getting a “target value must not be null” when running the code. We’re using when the mouse is clicked on anything event, and it seems that our “target” object parameter is not being recognized in our “prepareToShoot” method. Any clues or advice? This worked for me in the past with the older version of Alice and the same code, but not now.
