WWW:Mechanize with Menu

Hi!!
I am trying to do a robot using WWW:Mechanize but the page that i want
is done with frames and menus. The login page is the third page from
start. All pages are dinamacally with asp.
Can I do this using Mechanize or must see another else.
I a newbie using this and Perl but i have programmed in C so it is not
so different for me

TIA
