I am using a simple button in a WPF application running on Windows 10 using MVVM pattern to execute action on click with command binding using touch monitor. What actually happen is sometimes the first time command action is not executing on touch and it is working correctly after second touch onward.
I have verified that the TouchDown and TouchUp event is working correctly all the time (first and onward).
With mouse everything is working well.
The button is present in a Dialog box, I was wondering if it could be associated with any kind of focus management but can't find out ? Please help!

What type of WPF app are you using? (.net framework, .net core 3.1, or .net 5). Could you post some code that shows this issue? TouchDown and TouchUp are routed event type. Routed events will pass the event to everything under the control that is clicked. Is it possible another control is marking the event as handled so it does not make it to the button?

In my case the problem was RealTimeStylus for WPF Applications that should be disabled on Windows 7.
