But this an example in the Zope book and should work correctly, i even did
this with IE5.5.
I have been quoting Zope book examples wrongly before, but this one should
behave correctly.
I really don't see what the browsers have to do with it and the answer that
Dieter Maurer gave surprises me.
Could someone explain it a little more?

Do you use this form from a method or from a document?
