$$LoginUserForm : How to specify target frame

Hi there.hopefully just a small question.

i would like to specify the target frame for this system form, but whatever i try ( _parent, _top, “Framename” ) do not work.

does anyone has an idea ?

The problem is that this application has a three frame frameset and at the time when the session expire i would like to ope up the login form as a substitute of the frameset.

any ideas welcome

Regards
