I am currently using

That's great to know.

For the record, I had searched the manual referenced above but sometimes 
it is hard to find the answers to specific questions like this and the 
'Project Monitor' issue Brian helped me with earlier. Little issues that 
prevent you from getting your feet wet.

I feel comfortable now, got my togs on, and raring to go :).
