NIS2010 Main window always open when switching users

Hi,

 

I am running NIS 2010 version 17.5.0.127 on XP Professional SP3.  This is a box I use at home with four users (me, wife and kids).  Whenever we switch users, the NIS main window is always open in the user's session.  We close the window but when we switch users again, the NIS window is open for the next user.

 

There are no errors or alerts.  The window is just open.  Is this a feature?  Is there a setting where this functionality can be disabled?  I can't find any reference to this anywhere.
