Hello,
i have the following Problem, I've created an short example Project:
The attached project uses CustomPopUpWindowAction. This may not be a problem in Prism.
This is not related to Prism but rather how WPF handles focus during touch on a double click (double touch). The ListBox is keeping focus, so you have to give focus to the popup before you can close it with touch. Change your event to MouseUp and it will work.
