I have been able to set up an external monitor for my laptop successfully in "extend" mode (actually using my HD TV) with Vegas 12. When doing multicam editing, I can view the different camera angles on the external monitor just fine, including the mouse cursor which I can move around as normal. However if I try to edit and select a camera shot by clicking on the shot I want, the take is not selected (no blue rectangle) and I get the message to click ESC to get out of full screen mode.
Is there something I have to select in settings or preferences?
