Newbie struggling with inserting Studio Instruments Drum Kit in Home Studio XL project

I've been searching for a post on this but nothing hits it exactly...  I am trying to insert a Studio Instruments Drum Kit pattern into my project.  As instructed in another thread, I have created the track and then dragged the program into the track timeline from the plug-in interface.  When doing this, it adds like 8 new tracks and in the last one, it puts a few measures of the drum pattern.
 
Questions:
1)  Why does it create a whole bunch of new tracks with nothing in them?
2)  How do I get the drum pattern to continue indefinitely?  I am just trying to prototype a song idea and want this pattern to play throughout the song.
 
Thanks in advance for any help...  Been sitting here for two hours trying to figure it out and need some help!

Welcome, Chad.
On question one, I have never seen that sort of behavior. It's usually a straight forward process.
Can you give more details on your scenario and procedure? If we can replicate it, maybe we can figure out what is causing that.
Include system specs, and as much detail as possible.
As for question two, hover your cursor over the right edge of the MIDI pattern (in the track view). It will turn into a little handle. Click, hold, and drag it out to the right for as many measures as you want.

First of all, thank you guys for the support... Much appreciated.  Also, apologies for my lack of appopriate jargon to help accurately describe what the heck is going on...  As for reading the manual...  I have tried that to no avail.

RobertB, Here is some more info:

- Windows 7 Ultimate, 32-bit
- Intel Core2 Quad 2.4GHz
- 4GB RAM
- Sonar Home Studio7 XL
- Plug-in is the Studio Instruments Drum Kit included in the XL package
- Tascam-122L Audio/MIDI USB Interface

From the insert track menu, I select "Instrument Track" and point to the SI Drum Kit that shows up. The MIDI track is inserted and I open up the plug-in interface. I select the beat and drag it onto the track timeline. (See 3:35 at this Cakewalk video: http://www.youtube.com/watch?v=UquKaN5Ruio if you want to see where I'm dragging from).

When I drag it onto the MIDI track, instead of pasting into that track, it creates 9 new tracks, and on the last track is where it actually pastes the audio. The other 8 tracks remain empty - including the MIDI track that I inserted initially.  I notice when I try a different beat, it inserts a different number of tracks...  But it always inserts extra tracks... some of which are empty.

I did hover over the clip to drag it along the timeline.  While I can extend the clip, the sound doesn't extend with it. i.e., it still stops at the oringal spot.

If it helps to post screen shots, I can do that.  It seems like it should be so much simpler than this :-(

Chad, have you downloaded the 7.0.1 update from Cakewalk support?
Among other things, it corrected a problem whereby extra tracks were created when manipulating MIDI clips.
This seems somewhat consistent with what you are describing.

You wrote that you are getting 9 new tracks.
I'm guessing the first 8 are audio, and the 9th is a MIDI track.
What are the inputs and outputs of the new tracks?
Guessing again, but I believe they are probably not associated with SI Drums, and this is why when you extend the clip, it has no effect on what is played.

Download that update. I think we are chasing symptoms of a bug that has been corrected.
