This is really strange and at the same time interesting issue and we would like to get to the bottom of it. So first we need to make sure that we have the right project in which the issue can be reproduced. Therefore I have created a project where I have tried to get as close as i can to your scenario and it would be great if you can check it out and let us know if the issue can be reproduce in it.
Please note, that right now we cannot get our hands on Surface pro 2 in order to test the issue, but I hope soon we will be able to.
Meanwhile it would be great if you can let us know what versions of the Operating System and .Net are installed on the tested machines as well as if they have any touch monitor (like the Surface pro 2).
