[xmonad] XMonad is not playing well with floating windows

Hi everyone, I'm quite new to XMonad and haskell itself, so I really don't know if it's a problem of my configuration file or it's the default behaviour of XMonad. Everytime I make a window floating, the tiled windows in background swap between themselves, without any reason or fixed rule. If I replace them in the order I want, they re-swap as soon as I move/resize the floated window. I'm using Linux Gentoo and XMonad 0.8.1. Thanks in advance. -- Massimo Gengarelli <massimo.gengarelli@gmail.com> Computer Science student @ http://www.unibo.it . http://massitm.sohead.org <-- my personal, outdated, website.
