[Squeakland] Beginner's question: I can't get Squeakland plugin to work

[Rudy Zalesak]

I am a squeak beginner ( a parent who wants to try the system
out for my kids). I have tried to run the projects on the Squeakland
site, but all I get is a walkback window that
says:

message not understood: useTempChangeSet

I have tried it with both the Mozilla browser and IE6 with the
same result. What's wrong?
