I have been using VCam for some time and found it excellent. Yesterday I upgraded to version 2.3 and although the VCam interface still appears to be working, when I select XSplit VCam in Skype or Zoom there is no picture, just a black screen. Obviously Skype and Zoom both think there is a camera there as there is no error message - it is just that no picture is being transmitted. I have reverted to version 2.2 and all is well again, so the fault is with the new version of VCam. OS is Windows 7.
