I have tested my project on Windows XP Virtual PC machine and also using TeamViewer but still I am not able to reproduce it. Maybe it can't just be reproduce in my project. It would be great if you can test the attached project on your virtual machine and see if the issue is present in it. If not can you, please put together some basic code where it can be reproduce, so we would be able to investigate it and fix it?
Also any information about the window in which the DatePicker is could be helpful.
