Very useful that there is a zoom of the preview in Vegas Pro 20. I've already made a lot of use of that. Is it also possible to move the zoomed image with the mouse?
Sure. Press the mousewheel button and keep pressed whilst moving the mouse.
Hey Mike --
When I press my mouse-wheel button, Windows 10 temporarily hides Vegas (and the preview window I clicked on) and shows me a history of windows (and active windows too). No ability to just scroll around the zoomed preview window. Here's an example of what my desktop looks like after depressing the scroll-wheel on my Vegas preview window: (ignore the "recording saved" box)
Is there another sequence to scroll around the preview window when zoomed in?
It was set to "Application Switcher" -- I'm sure I thought I was clever some years ago when I set that, and now I mistakenly thought it was standard Windows behavior.
