I recently upgraded to the latest version of Camtasia for Windows and I am experiencing a bug with Extend Frame. I have a long period of screen video with no movement, which ends when the mouse cursor moves. I wanted to extend the still period by a few seconds to sync up with my voice. However when I do so, the preview displays the extended frame to be the first frame of movement after the still period, and when the extended duration ends, it reverts to the correct (still) frame. This happens regardless of the duration I choose or even what frame in the still period I extend. When I batch production the mp4 displays the extended frame correctly, so it is only a bug in the preview. Is there anything can be done about this? It's making editing difficult.
