[Doggiebox] Another observation

Is it just me, or does DB like to "stutter" a little bit on the first playback after opening a song for editing? If I start a bar, or a whole song, the timing is very messed up. If I stop, then play the same bar, it's OK. This is true until DB makes it's way through the whole song. It's a bit annoying. It's like there's some sort of caching or something not going on that requires DB to think about all the sounds again. Another question: is linking an active feature yet? If so, how to make a link? I've got that next nskit ready to go, but all the sounds are embedded.
