Recording the Metronome - Old Question - New twist - SOLVED!

Original issue below (I had to fish through a LOT of similar questions to find this answer):
 
Thanks to Dan Tarbill for this solution:
 
The audio metronome won't render on mixdown (today), so you are left with a number of different hacks to get around it. What really makes the most sense is to just do a click track of your own. But, I had a thought...

* Send the audio metronome to a MetronomeBus bus.
* Set up a MetronomeTrack audio track.
* Put a Sonitus compressor in the MetronomeTrack fx bin.
* In the MetronomeBus, insert a Send to the MetronomeTrack compressor's side-chain input and crank up the send level.
* In the MetronomeTrack's compressor, solo the side-chain input.
* Arm the MetronomeTrack for recording
* Rewind to the start of the project and hit record to capture the audio.
   
 
 
Original issue:
 
I make a lot of click tracks.  The way I do it is to import an existing recording of a choral or vocal piece, create a tempo map, and create the instrument and/or vocal tracks required for the performance piece (using the orginal recording as the perfect guide).  Often times I use this to provide brass support when we don't have the players for a piece. 
 
I create really excellent tempo maps by having the tempo view open, and drawing straight line tempo changes as required.  I find this to be a better way than the prescribed method of beating out a quarter note MIDI map, as it does not produce the zillions of micro tempo adjustments, and matching a ritardando is very simple.  Once you get used to it you will find its faster, and more consistant (a good drummer will hear very minor variations in tempo, and it will drive them crazy).
 
Anyway...
 
Before going any farther, I have to add that I use the Audio metronome - It's built in and always there - no setup, no hassle, instant metronome.  I'm busy, and need to optimise this workflow.
 
Now I have this great tempo map, and a metronome that plays precisely to the beat\tempo.  I then assign it to a bus.  Very handy.
 
Now, according to one Noel Borthwick:
 
"Yes you can most certainly print the output of the [ click to a track. Just assign the [ to a bus, set source category to buses and then bounce that specific bus to a track. You don't even require realtime bounce for this if all you want is the [ click. "

The only problem is that any time I do an export or bounce, the metronome goes silent.  Even a realtime, audible bounce - Nothing - Metronome does not sound.  Anyone have an idea on how to remedy this?  Is Mr. Borthwick talking about the Audio metronome, or a MIDI one only? 
Thanks,

Just discovered  there are pre - recorded metronome groove clips in Sonar's sample content folder [Sonar 7 anyway]. Who knew? Just drag 'em in and there's your audio click track. Different time signatures too. The 'ping' version is exactly the same as the Sonar metronome.
