Virtual mic output stops when minimizing Wirecast

Using Beta 14.1 on Windows 10 with virtual mic and camera output

Minimizing Wirecast stops the virtual mic output, and re-opening the window fixes the problem. Wirecast can stay in the background and the output works, just can't minimize the app. 

To test:

1- Enable the virtual mic and start the virtual camera output

2- Go to Windows Sound settings and choose the Wirecast virtual microphone as the input

3- Talking into the mic will show the sound volume under "Test your microphone"

4- Minimize Wirecast, and try the mic again, no output is shown
