MS SQL Server connection dialog location

In MS SQL Server 2008, my connection dialog has somehow moved to an inconvenient location. I have a portrait monitor and a landscape monitor. I no longer open SQL Server in the landscape monitor because then the connection dialog opens off screen.

I've tried everything I can think of:

1. dragging the dialog box to center screen then opening a connection, then closing and reopening SQL Server
2. dragging the dialog box then canceling the connection
3. both of the above with SQL Server Maximized as well as Restored.

Somewhere in some config file there must be a setting that says "always open the connection dialog at this location". Where is that setting? Or is there another way to fix this?
