I am thrilled that Athena + Larch works at all for anyone besides me.
That by itself seems like a triumph!
I will be happy to entertain bug reports about Athena-using-Larch and I
have no doubt that there will be many. It is, at this stage, very
loosely tested software.

Athena on Windows always seems dog slow to me, even on a pretty beefy
computer. In truth, it's been a long time since I last tested
Athena-using-Larch on Windows. Next month, when I am back from my
holiday, I'll try to find some time to look into it.
