Hi Jeff i am having pretty much the same problem only my login is displaying on the page not on the widget.
my first problem is my login page it keeps loading till is time outs... why is this happening is because on my, theme my login setting basic i have change the ID to my login page ID witch witch it keep the page loading i find out this problem is coming from my WordPress under setting >> Reading , static page is selected to my login page witch is my main.
my second problem is the same one as Cristiano when u type a wrong password it direct you to a "mywebsite.com/?ction=lostpassword&instance=1"
witch it display a list of blog post. am not using a widget am just using a short code on my main page content ' at the moment i am also using a director plugin to avoid this problem but is not helping much
