Fences and Snagit?

I use Snagit by TechSmith to record screenshots and videos from my webcam and desktop. I do this mostly for training videos. It's designed so one can record what's on the screen, switch to the webcam, and go back and forth. The video thus recorded can be further edited using the TechSmith product Camtasia.

The problem is that while that's the way it's supposed to work (and the techies at TechSmith assure me it does), it doesn't for me. My recordings work fine for the first iteration, whether that be screen or webcam, but when I try to swap, the video recording freezes. Microphone recording works fine as I swap back and forth between screen and camera, but the video recording freezes at the first frame of either after the initial portion. Thus, the first video works, but each time I go to swap and record, the video freezes at the first frame even though the audio does record.

Since fences does do things with the desktop screen, I was thinking that maybe there might be a problem slinking around there when it comes to using Snagit to record my videos. Anyone... thoughts?

(PS - I'm running on Windows 10 Home (64 bit) - always up to date.)
