I used to use it to dump out a year's worth of months with blank
lines, print them out & stick them on the wall as my calendar (which I
write on). Why? I don't have to turn the computer on to see them, and
paper never crashes.  I suppose this is me <https://xkcd.com/1172/>.

It certainly used to. I *could* reproduce this problem in 22 (22.1 I
think) so it may have been 20 or even 19 that worked but I did used to
do this.

My prior email which you may not have got gave this as running on windows.

I didn't. There's no mention of 'diary' in my rather trivial .emacs file.

Running on windows server 2008 R2, from the splash screen: GNU Emacs
24.5.1 (i686-pc-mingw32).

Happy to answer any questions (esp reproducing prob with M-x diary if
that helps)

cheers
