Is there a way to prevent my clips (audio and video) from shifting to the right every time I import new content? For example, I may have six tracks full of "stuff", then split the set and move it over a bit so I can squeeze in a small video clip as a transition. When I drag in the transition video to an empty track, everything else on ALL tracks to the right of it shifts to the right a distance equal to the length of the imported video. But, that's not what I wanted... I don't want those other tracks to move. I worked so hard to put them exactly where they're at :-) .

If I activate the little padlock symbol on the tracks I want to keep static, I can't add any new content at all, even to a new, unused, unlocked track. So, that's not the fix. Hoping it's a simple setting I simply couldn't find. Any help is much appreciated!

Info: I'm using Movie Edit Pro Premium (the "About" dialog states this is version 16 but is noted as 2017 in my Magix.com account settings online) with Windows 10 Home version with all the updates in place for both.
