Since I was upset with Kmail always opening in fullscreen, I decided to let go of fixing things, and instead force it to do what I want through `Alt f3` "configure special window settings".
So I just do that, and click OK, in the dialog, and then the screen flashes as it usually do in that specific situation, and then the "settings" window is gone, just as it does nowadays, and then I go in "settings" and "windows rules", in order to set the specific parameters I want it to assume, and then: dah-dah! Nothing. Nothing it registered at the name "Kmail", or "Kmail2" as the dialog called it. I already have four of them, three of them long standing, and one newly created, for firefox, which was stubbornly opening in very small window, and that I had to tame (as a matter of fact it started behaving like a bad application a few week ago too). Anyway, I usually know how it works. The long standing are emacs konsole and okular and are of the "application" persuasion. The new one is of "window settings" sort. Anyway, following these directions, it doesn't work, doesn't do anything; but it duly flashes the screen, showing it did do some real work in the configure window setting line. Weird. I tell you if I have more data. Chris PS: I did `rm -rf ~/.kde4`, in order to remove all easy and safe to remove settings and config things, as I've been recently suggested to do, some times before the above thing.
