Setting video capture properties no longer works in OpenCV 2.2?

Prior OpenCV 2.2, I was able to do

VideoCapture capture(0);
capture.set(CV_CAP_PROP_FRAME_WIDTH, 640);
capture.set(CV_CAP_PROP_FRAME_HEIGHT, 480);

in order to modify the frame size. But after when I compiled my application against OpenCV 2.2, setting the properties no longer works (the video is displayed correctly though). If I do a get of these values, 0 is returned. And if I look at the size of the captured frame, it is 160 x 120.

I searched online but most of the posts were about the problem in Linux whereas I am running Windows 7 64-bit. My webcam is a Logitech QuickCam Ultra Vision.

Is there anyone experiencing the same problem? Or no problem at all?

Thanks in advance!

This problem has been solved in OpenCV 2.3, even with my old Logitech QuickCam Ultra Vision webcam.
