Hi @magnuslp, thanks for your query and apologies for the delay. In the WPF app, gaze aware buttons are created within a window context which makes them react to gaze.
When the virtual window is created, this resembles a window on its own which logically covers the other gaze aware elements if its Z-order is in the foreground of the associated WPF window.
Hence the buttons will stop working since they are “occluded” by the virtual window. Could you kindly explain what is the purpose of the virtual window, just to capture gaze regardless whether gazing on a button or not? “global interactors” may be a more useful strategy in this regard.
