Version: (using KDE 3.5.8) Installed from: SuSE RPMs Bug 19369 fixed this in r109466 back in 2001, but it looks like it broke again when kwin_iii was merged in r251608. That code (which is the same as HEAD) does wheel exclusion on input to the active window, where the bug is about mouse scrolling giving focus to inactive windows. Here is a simple patch that makes the focus not change suddenly every time I brush my palm against the scrolling portion of my notebook's touchpad.

SVN commit 817599 by lunakl: Don't activate inactive windows on wheeling over them. BUG: 161174 M +1 -3 events.cpp WebSVN link: http://websvn.kde.org/?view=rev&revision=817599
I considered this a feature, not a bug. Can this be re-opened until there is a config option for this?
No, there's really no need to go as far as having mouse wheel focusing configurable. If you want an action for focusing a window window without raising it, set one of the mouse actions that way in kwin configuration.
As there was no reply on bug 164261: How does one do that?
For me making an underlying window active with the scroll of the mouse was a useful feature in KDE 3.5.9. Could you please make the mouse wheel focusing configurable? There is no action for mouse wheel in kwin configuration. Many times I have to type text from some web page or program into a kwrite window. Scrolling the mouse wheel in KDE 3.5.9 makes the kwrite window active but not raised, so I can use the kwrite window under the top lying window. In KDE 4.1.3 I changed the policy from "Click to Focus" to "Focus Follows Mouse" but that has other annoyances: if I move the mouse away when typing my root password into a KDE su window, my password gets typed in another window. So I changed back to "Click to Focus". Hm, wait: I've just changed Window behavior:Window Actions:Inactive Inner Window:Middle button from "Activate & Pass Click" to "Activate". And that works as scrolling the mouse wheel in KDE 3.5.9. So I'll use the middle button click to make active without raising. Although I prefer scrolling over a middle button click (scrolling feels easier).
I'm wrong: no need to change from "Activate & Pass Click" to "Activate". Middle button with "Activate & Pass Click" also makes active without raising.
