[xmonad] hhp breaking middle-click

[Gwern Branwen]

So for many moons I have been plagued by a bug wherein middle-click
ceases to function. Normally, middle-click in X will paste the current
selection. This is terribly handy, especially given one only needs to
highlight to enter text into the current selection.

Closing out all visible apps didn't seem to solve it (although for a
long time I suspected Firefox of causing this problem); I had to
restart X or log out.

Recently I tried removing hhp* from my startup scripts, and since
then, I don't seem to have triggered the problem. (This may or may not
mean anything; the problem is *very* intermittent, which makes
diagnosing it difficult.) Hence my question: has anyone else
experienced this? Did removing hhp seem to work for you too?

* hhp is analogous to 'unclutter'; it hides an inactive mouse. You can
find it in Andrea Rossato's 'xmonad-utils' package on Hackage.
