I am having extreme difficulties getting a ProWindow to display where I want it to. It doesn't matter how I define the window (either in XAML or programmatically), the window always displays in the same location that it was last located when it last closed. I can set the WindowStartupLocation to "CenterOwner" with the Owner set to the Application.Current.MainWindow, which should open the window in the center of the Pro application. However, that doesn't work. I can also set the owner to be the center of another window and that doesn't work. Additionally, just for testing purposes, I can set the WindowStartupLocation to "Manual" and define a top and left for the window, but that doesn't work. It doesn't matter what I do, the result is always the same. The window just opens in the last location that it was closed. This is clearly a problem. As an fyi, I am developing with the C# SDK for ArcGIS Pro in 3.1.1. Does anyone have any idea what could be causing this problem?
