Thank you for the response!
I currently use logmein and could activate the iCam Source with that, but at the same time I could just open Photo Booth and view the cameras without iCam. Seems like a rather clunky solution.
Unfortunately for me, having the cameras active all the time is a deal breaker and I'll be retiring iCam until it is addressed.
Again, thank you for the response and the hard work you've clearly put into this application.
