Unable to load both forms

Hi all,

I have a problem with my code when I execute Gui.py, In my view there are two objects created, the first one call LoginForm and the second one calls errorForm. The Loginform will be showed but the errorForm doesn`t show and there is no errormsg visible.
Now i`m really stuck and hope I can find the help here. Below are the sourcefiles. My goal is to popup both forms.

Source Files:
Gui.py (http://pastecode.org/index.php/view/40b50e6c)
login_screen.py (http://pastecode.org/index.php/view/28059b2b)
error_screen.py (http://pastecode.org/index.php/view/b4b43486)


Kind regards,

Bartson
