I am trying to load SquirrelMail inside a from (My frameset is a set of four frames together)

I gave the Frame where SquirrelMail  has to load a name of “MailArea”

I did change the _top  definition in the configuration to MailArea, however I can not signon to SquirrelMail inside the frame.  If I open the SquirrelMail inside a browser it works fine.

 

Does anyone has any idea?
