thanks for suggestions<br><br>turns out that my problem was that I was using an old 3.8 image<br><br>I learnt from the book how to file out and file in - as soon as I tested my code in the 3.9 image it worked fine!<br><br>
A friend sent me some other information from the bugs site pointing out a bug in SimpleSwitchMorph in earlier versions:<br><a onclick="return top.js.OpenExtLink(window,event,this)" href="http://bugs.squeak.org/print_bug_page.php?bug_id=3530" target="_blank">

Hi Bill --<br>The game works fine in my image.<br>1) The first thing I would look at is when the debugger comes up I<br>would select the second line from the top of the list that is shown<br>in the top pane of the debugger. When you do that the debugger opens
<br>and will have the offending message highlighted. I would select the<br>object that is getting that message and cmd-i ( or ctl-i ) which<br>brings up an inspector which will show you if you really have<br>aSBECell or not. If you are not getting the right object there is
<br>probably something in the code that you did not copy correctly. Did<br>you type the instructions in ?<br>2) same steps as one.<br><br>By the way the code for the examples can be downloaded from<br><a href="http://squeaksource.com">
