Thanks for your help
Unfortunately im now even more confused. :(
I tried the help function, which was helpful but didn't address the issue at all.
I then tried the enable button, but rather than being seletable per track it is either selectable for all or none, i.e. it wont isolate any individual track.
here's a screen shot of what im looking at when i click the speaker sign in the bottom right of my comp.

One thing i forgot to mention, if i were to record the click on track one, then guitar on track two, the click recorded on track two would not be in time with that of track one, there's a slight delay.
