Drum editor question

One simple question:

How can I get the Drum Editor to be highlighted so I can click it on and use it?
I’ve tried everything I know and can’t get it highlighted so I can use it. (Cubase 6)

Create a MIDI Track or Instrument Track then create a Part on the Track.

Thanks. I did figure that out eventually.

The problem I’m having now is when I get a setup I like with Bead Designer and insert it in the track, although it was in time, after inserted, it is out of sync with the other tracks.
This is after I have used Time Detection and the clicks are in sync.
Any idea why I’m having this problem?
