Why is a Silverlight button hard to click by touch on an HP Touchsmart?

Question

I am using Silverlight to develop an application that we anticipate will be used heavily on touch screen monitors in the healthcare setting. I am finding that simple controls like Button, or even simpler primitive controls that I've written myself to capture mouse events, are very flaky and unresponsive on an HP Touchsmart. Many times clicks do not even register, but the behavior is entirely unpredictable.

Any idea why a plain old Silverlight button is hard to click by touch on an HP Touchsmart?

Answer 1

I'm having the same issue with my HP Touchsmart tx2. I can see that MouseLeftButtonDown/Up are firing, but the Click event is not.
