Adjust combo viewer window position/click loop while playing animation

[RipleySometimes]

The animation plays, and stops when the window or loop checkbox is clicked. Steps to repeat: Navigate to tools, select combo viewer, play combo, click window and drag/click loop box. Consider allowing the functionality to adjust the window while playing the animation. This allows you to see the TAE events in the timeline. The loop checkbox should be clickable or grayed out as the animation plays. Pressing the loop should not pause the animation.
