HTML Forms not working in precompiled version

[mma]

Hi everybody,
on a aspx page, i have a HTML form that on submit calls the aspx page
itself.
works fine in asp, in .NET 1.1, non precompiled .Net 2.0.

In the precompiled version of the .NET 2.0, the request.form in the
request after submitting the form is empty(request.form.count=0).again,
the code runs smoothly if the page is not precompiled

any ideas apprecicated

thanks in advance
