Ok, silly question. In 11.2 my mouse moves to the active window and its driving me mad 
I’m quite sure I didn’t turn this on, it’s been doing this since the first login. I can’t find this setting.
There does not appear a way of achieving this in KDE. Is this Gnome, perhaps a Compiz setting?
Oh, sorry I forgot to mention this. I have Gnome and Compiz.
On 11.1 I ran Compiz-Fusion 0.8.x and I don’t remember an option like this. Now on 11.2 I run 0.7.x and I can’t find it. I’ll check again.
Nope, can’t find it in Compiz either.
Well it’s certainly not standard behaviour so it must be something in your settings. You say it’s been doing that since first login, and also that you used 11.1 before 11.2. Fresh install or upgrade? Same /home as before?
Create a new user, login is that new user and see if the problem persists. If so, you will need to clean out your homedir to remove old settings causing this behaviour.
I did a fresh install and I only copied my data from the old Home folder. No settings at all. Now it was gone this whole weekend. Back at work, it didn’t do it this morning. Since I opened a RDP session to a win server it’s doing it again. I use the rdesktop + tsclient software for this. I’m not very sure it’s because of the RDP session, but I am quite sure it wasn’t doing it this morning and now it is. I almost moved a network folder because of this. I wanted to click something, the RDP window became active and the click was on a folder, when I released the mouse button it already was over another folder. Very annoying.
It’s doing it in and outside the RDP session.
Yes, I’ll try this in a last effort. Thanks.
Since it starts at a remote desktop session, it looks like there’s something wrong in the configuration in that area.
Found out it occurs when I try to zoom in (compiz) super+shift+scroll wheel I believe.
It doesn’t zoom, but it pops out the Slab, Gnome Main Menu. And it starts homing in the mouse cursor to the active window. Haven’t found a way to disable it other then restarting X
