xmessage is definitely installed. I tried introducing deliberate syntax
errors in xmonad.hs, and mod-q then pops up a message. I also tested
"xmessage test" from an xterm.

~/xmonad.errors is empty. ~/.xsession-errors contains the following:

Warning: Cannot convert string "nil2" to type FontStruct
xterm: cannot load font
user error (createFontSet)
No running windows found
user error (createFontSet)
user error (createFontSet)
user error (createFontSet)
Waiting for Emacs...user error (createFontSet)

user error (createFontSet)
user error (createFontSet)
user error (createFontSet)
user error (createFontSet)
user error (createFontSet)

user error (createFontSet)

This is after a fresh log-in to xmonad, with the following ~/.xsession:

***** ~/.xsession *****
export PATH="~/bin:$PATH"

I then ran Emacs to view those files and copy them into this email, and
started an xterm to test xmonad.hs as below.

I get the following output:

*****ghci, :load xmonad.hs*****

Ok, modules loaded: Main.

Could those createFontSet errors maybe indicate something going wrong with
the fonts used to decorate the windows?
