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. -- gwern
