Frequently Asked Questions...

    
Q: Why do I get an error that the observer doesn't know how to run my
   button?

A: In the new version, you need to put start or stop in front of the
   button name.  
   Example: To start or stop a button named Go: startGo or stopGo.

    
Q: What is the Edit/Calibrate Graphics menu item and what can it do
   for me?

A: There are many ways to use Java to draw to the screen, and some of
   them are faster than others. We've included three different schemes in
   StarLogo because unfortunately, there's no 'fastest' drawing scheme
   for all computers. Calibrate Graphics tests each of the drawing
   schemes with various numbers of turtles to find out which one runs
   fastest on your computer. It then saves this information so it can be
   used for each StarLogo session on that computer. You'll only need to
   run this once when you put StarLogo on a new computer, and then the
   graphics will run as fast as possible. If you don't run Calibrate
   Graphics, StarLogo will make a guess at which drawing scheme should
   work best (based on what works best here at MIT) which should give you
   decent performance.
