Hi, there and thanks. Rebooted many times.
1-Staff is important because I do 90% of my work there.
2-That said, dragging, cutting, copying, and pasting in the timeline isn't working right.
It appears upgrade is the next thing to try. This is still an interesting mystery, though. Code does not just suddenly stop working. There must be some hidden (intentional or unintentional) shortcut that disables the function. I was hoping Cakewalk would jump in with some advice, but perhaps it is just as mysterious to them.
