A few moments ago on my F15 desktop appeared window with title "Authentication" and two user-fillable fields within, "Name" and "Password". Nothing else. At this moment I not expect from none of cca 15-20 running apps this question window, nor from several running applets (thus, probably some crackers want access to my credit cards ;)
How generally I can state which process display it? I would expect, when right-clicking on window top title bar, some item as e.g. "window properties" - where would be possible find info about process displaying this window. But there isn't nothing of the kind. Thus, is there other way discovering this?
I forgot mention, I'm now in F15 using XFCE (but IMO in Gnome window manager has not capability too).
Thanks, Franta Hanzlik

Try the "top" command, and re-arrange the display order to show the most recent processes at the top. The dialog box may be near the top of the list, and you can use that to work out where it came from.
But I'd be tempted to cancel the request, and see if it comes back again, or if something else happens.

The process displaying the window is actually the X server, acting on behalf of some client which may not even be local to your machine, but you might be able to get some clues using xprop and xwininfo.

In f15 the gnome and xfce window managers both seem to set a window manager hint that includes the process ID so you can probably get this by running xwininfo and clicking the suspect window:
$ xwininfo -wm
xwininfo: Please select the window about which you would like information by clicking the mouse in that window.
xwininfo: Window id: 0x2200005 "bmr@bmr:~"
Window manager hints: Client accepts input or input focus: Yes Initial state is Normal State Displayed on desktop 0 Window type: Normal Process id: 2157 on host bmr.fab.redhat.com Frame extents: 1, 1, 28, 2
$ pga 2157 2157 ? Sl 0:05 gnome-terminal 24640 pts/0 S+ 0:00 grep --color=auto 2157

Tim, Patrick, Bryn - thanks for valuable tips. xwininfo and xprop are both capable return PID and hostname of window controlling process, which is all I need.
Btw, my cryptic process was LXDA Policykit Authentication Agent (/usr/libexec/lxpolkit). I not know why it is launched from XFCE session, maybe some relict from my previous experiments when I was searching some replacement for Gnome 2.x. Fortunately, this applet is well described in XFCE Preferences menu (in contrast with crippled ones as "load color profiles", "unlock certificates" and other weird named applets, for which is problem locate destination file), thus wasn't problem disable it.
