In som environments I get an error when I try to display a user form
from a VB6 com addin in Outlook.

Run-time error '406':

Non-modal forms cannot be displayed in this host application from an
ActiveX DLL, ActiveX Control, or Property Page.


The code adds a button to the Standard toolbar. The eventhandler for
the button loads och show the user form.

Since the form has no parent window, I dont think it's posible to
display it as a modal form.

The code works just fine on some machines. I'm using Outlook 2003.

Please help!
