Spoken like a true accountant! <VBG>
When I install FSX, I'm going to set up an A4 ring binder with sections for -
(a) FSX Set up tweeks and configs
(b) Added aircraft
(c) Added scenery
(d) Panels and gauges
and whenever I update FSX I'm going to write down what I did in my log.
That way when my machine goes bang, or when I get the new Vista machine next year, I'll be able to set it up without relying on my failing memory.
