P6 Dialog Box Appears Off Screen (Box Not Visible)

When trying to add a Notebook Topic to an activity in P6 Professional V16.1 (Citrix environment), I click the add button and no box appears (image below). This sometimes occurs with the "Add Relationship" dialog box as well, but I can see the bottom edge of the box at the top of my screen and can pull it down. I am using a laptop with docking station and 2 monitors. I have tried closing P6 and reopening and have also tried closing and reopening P6 with the laptop off of the docking station.

Is there any way to reset the default/last location of the dialog box (ie - a config file or something of the sort)? Maybe another work around?
