With this configuration:
Logitech HD Pro Webcam 910 and Logitech Webcam Software installed on Parallels 10/Windows; SKYPE also installed on Parallels 10/Windows. Both devices on Windows Taskbar. 2 monitors with OSX 10.9.5.
Webcam works OK as stand-alone image capture device.
Starting SKYPE from WIN 8.1 taskbar turns taskbar blue on one monitor and window with 'Switch to a Microsoft account on this PC' Another message is 'Sign into each app separately instead (not recommended)'. Pressing 'Cancel' returns SKYPE screen, returns to MS account screen released. Seems only solution is to quit Parallels 10.
Actually, quitting requires CTRL-ALT-DEL in windows to shutdowm SKYPE and MS Account window.
Quitting SKYPE (right-click, close window) and then quitting Webcam returns disconnected from SKYPE message from Webcam app.
Do I need to setup a Microsoft account or is there another way to use SKYPE & Webcam. Or can I do all this in OSX?
