I use a Dell SX2210 monitor with integrated webcam. It worked with Win7 and Win8. Since upgrading to Win8.1, the webcam no longer works within metro\modern applications. The screen appears blank. It still works within desktop apps. MSFT forums offer some solutions but they are not ideal.

Dell needs to develop a driver for this camera and Win8.1 Are there any plans to do so?
