Visual style error

Hi,
My customer hit error while click on browse button. However, I can't reproduce in my machine and also my dealer machine.

Any ideas?

There is a known issue regarding themes and .NET controls as it relates to the DateTimePicker and Visual Styles. Try turning on the Windows Themes service and you may try choosing a theme other than Classic to see if the error goes away. You can then work your way backwards by going back to Classic but leaving on the Themes service and see if the error comes back. This is the first thing I would try.
