Thanks guys.

Now i think on it i have had problems with some display settings so it's probably the driver. I'll try using Ctrl+s in future.

As for the heirs, i think i did have 6 at one point but 'accidently' got the dross killed off and still didn't get any more for many years.

Impressed some of you get kings up to over 80 years old, all mine (admittedly not many) have died before 70.
