I have not been able to delve into this yet as I don't have a touchscreen. We have customers that are reporting that when we apply a skin touchscreen gestures no longer work. So, for example, pinch zoom and other functionality we support via WM_GESTURE/NOTIFY, WM_POINTERDOWN/UP/UPDATE and WM_TOUCH are all failing.

I previously posted about failures due to the DDEMLEvent window class not being filtered out and that I fixed that issue by adding my own filter. I am guessing that touchscreens support involves a window that is between "normal" windows that handles and forwards messages to the application.

Has anyone else noticed issues with skinning and gestures on touchscreens?

I also suspect the Microsoft Inking system would have issues too and will be looking into that since I think Inking and touchscreen support probably use the same underlying Windows technology.
