If it is happening to others, this can be very problematic. When I used to record rap/hip hop, we'd stack the heck out of vocals using just clips. If I had to delete a section, all was great because I would select the section across all tracks, delete the hole and all would still be synchronized. With this bug, you got a heap of trouble. Think about it.
Maybe I'm missing a setting or something. I know "Options|On Stop Rewind to Now Marker" gets selected every once-in-a-while and I have no idea how it happens. Errant keystroke or ghost in the machine/software.
