redirects to domain.com/#_=_

the module works great! After a hard struggle with fbconnect module, this one seems supereasy for installation and use.

the issue
===
after successfully login through facebook, the module redirects to www.domain.com/#_=_ . I checked the module code for '#_=_', but couldn't find it. is there a way to remove this and redirect it to domain.com alone?

thanks
