One of my clients bought and installed a new machine running Windows 7. My application appears on that machine with a horrible color scheme--there is a lot of white, and colors that normally distinguish different states (enabled, disabled, selected, etc.) all look the same so it is almost impossible to use the screens. Do you have any idea why this happens and how to correct it? Is it possible that the user selected the weird color scheme at the OS level? The application runs fine on all earlier operating systems. Thanks.
