Listen, I love Camtasia and I also use Screencast. But one issue is really bugging me. Is it possible to prevent the canvas from automatically and randomly resizing whenever I happen to move the mouse inside the canvas? This is very annoying to have to stop and constantly select Fit because I've inadvertently resized the canvas due to handling my mouse. I've gone into preference and see the lock but it doesn't stop the canvas from resizing if I accidentally pick my mouse up and click the left side of the mouse. I believe the canvas should only resize if I pick a different size, not just because I used my mouse.
