Why I can't turn off my computer.

This is my wallpaper.

I think it is the most exquisite picture of Vincent I have ever seen - and that's really saying something.

To try and help me shut down the computer, yesterday I decided to print the picture out. It took an hour of fiddling, changing leads on the printer and rebooting, and I finally got it to print. At which point I remembered why this wonderful and expensive "photo" printer is on my list for replacement. It prints in inaccurate (sometimes bizarre) colours, and you can see lines where the ink heads cross the paper. The picture came out dark and stripey. So I'm still having trouble forcing myself to log off.
