Thank you so much, Henrique. I am about to go away and am a bit rushed, so what you have told me is that I had better not touch it until I get back! And perhaps should consider Scratch. Or hold my nose and stay on Ubuntu for a bit. I'll deal with it next week and report back. > First, it tells me your specific motherboard and processor won't work > well (as in it will be quite crash-prone) *unless* you updated its > "BIOS" (really, UEFI) since about a week ago.

I'll report back if I am still upright and sane after all this!! Lisi
