Mozilla error on postback and validation

-----------

A Button causes a Listbox to desappear.

If no item has been selected on the Listbox,
all is OK.

If one or more items are selected,
I receive the following error
(about postback and validation)

Note:
on IE is all OK,
on Opera is all OK,
on Mozilla (1.5.0.1) I get the Error

Is it bug of Mozilla?
How can I avoid that?

--------------------

This is the error:

Exception Details: System.ArgumentException: Invalid postback or callback
argument. Event validation is enabled using <pages
enableEventValidation="true"/> in configuration or <%@ Page
EnableEventValidation="true" %> in a page. For security purposes, this
feature verifies that arguments to postback or callback events originate
from the server control that originally rendered them. If the data is
valid and expected, use the ClientScriptManager.RegisterForEventValidation
method in order to register the postback or callback data for validation.

This is the stack trace:
