In the code in "Additional Information" if You click in the <TD> that simulates
a button, the javascript code is not executed.
It works for Mozilla 1.0 to 1.6, IE and Opera.

since the <td> is no form element, name lookup does not search in the form. use
document.forms[0].Asteriscos and document.forms[0].Senha in the Tecla call in
the <td>.

note that the javascript _is_ executed, but throws an exception, check tools|web
development|javascript console.

however... bz, why did this work previously?
It worked because of this scope chain lookup mess (which we eliminated for
compat with IE?  Then why's it working in IE?)

Maybe IE does the weird-ass form-lookup thing that we do for form controls, for 
everything? That would explain it... Someone should test this...
This "someone" needs to be someone with access to IE....
Yes,
Asteriscos.value += "*";
and
Senha.value += Caracter;
in the code of the provided testcase will be executed without javascript error
reported in MSIE 6 (I checked with Microsoft Javascript Debugger as well with a
step by step debugging). There is no need to prefix form input control with
document.forms["FormName"] or document.FormName in MSIE 6. Even for submit controls.

So far, I have tested 8 cases related to MSIE 6 specific chain scope lookup,
trying to identify differences with Mozilla:

can be improved but it will do for now.
The standard version of Sun Java when installed through the automatic set-up in Internet explorer normally will pick up that Firefox has been installed and install the relevant adapter and it should help update to the latest version which I think is something like 5.0 but it can be worth-while removing sun Java and see whether the Microsoft Virtual machine works without the problem, as sometimes if one version of the Java system works and the other does not, then it can show that you may be better off using the Microsoft Virtual machine which I believe has to be downloaded and installed manually through microsft.com 
In Internet Explorer, named form controls are visible in the global scope. This
is wrong. 

If someone visits this bug, then (s)he can fix this problem by following
timeless' recommendation in bug 246197 comment #1.
