StarGazer - problem with settings in some apps

Hi,

Great product in general, however I'm having a problem with apps (Camtasia in Powerpoint the urgent one) defaulting to the SR300 Depth Camera and then just giving me a green screen with no other image when I'm recording lectures. Is there a way to make the virtual driver the default camera for all apps and programs? I can't find anything in windows, the Razer software or the programmes I'm using to do that.



Thanks in advance.
