[Zope] problems with msie 6

[Thorsten Harms]

Hi!

I'm quite new to zope and I have a little problem with msie 6:

I created a formulator form. When it is submitted a python script is 
called that validates the entries and then calls a zsql method that 
inserts them in a mysql table. With Mozilla, msie 5.X all works fine, 
but using msie 6 the entries are inserted two or three times. No error 
messages appear in the  error_log so I have no idea where to look.

(Zope version is 2.6.0, formulator version is 1.2.0)

Any hints?

Thanks in advance
