Thanks Dinesh,
For me this was a very interesting look at some of the inner workings of the OS. As I do a lot of back and forthing with programs, losing all the clutter with a log off or restart is just what I needed.
While in the Editor I spotted how to put a Run icon in the Start Up Menu, so that's 2 birds with one stone. Most excellent.

I'm not sure if this is the place to ask, but doing some reading on the items listed in this area I was wondering just as a piece of information, what this meant.
"If you enable this setting, certain notification balloons that are marked as feature advertisements will not be shown."
What on earth is a 'feature advertisement'. Surely Bill and the boys are not trying to flog us stuff from inside the system

Real good tutorial, thanks.
All the best,
Mick C.
