Thank you again. I'll look at the snap/magnetic settings.
In my case, turning off snap completely is not an option, because I want it to snap. Say, I have an audio clip that I sliced somewhere between beats, and I want to copy it a few more times else where in the timeline. In Sonar 6, I'd press ctrl and click on the clip and move the mouse, and I can visually see while I am dragging, it snaps to same spot between the beats in every bar I am dragging over (given snap set to one measure). In X3, it doesn't snap completely, it looks like it snapped, but when I wiggle the mouse it changes its snap location.
This is very frustrating, because I don't feel confident that it snapped where I'd think it should. then I go to every clip I copied and check their starting point, and they are all over the place.
