Hi new user here. i like to use the shift-command-T shortcut to move regions precisely from track to track. i've been doing it for a month just fine until recently i've noticed that when i move a region it overwrites and deletes the underlying region. it hasn't been doing this before and i think i must have inadvertently reset some preference. i tried the options in the "Drag" drop down but nothing has fixed this so far. i also tried to search the manual and the forums to no avail thanks for any help cheers m
