Hi All, I have a machine running FC4 with the latest updates (as of yesterday morning), although this problem has been happening ever since the machine was installed (clean install after full format incl /home). I am using KDE as my window manager. The machine behaves quite normally and I can use the internet, local applications, terminal windows etc, just as you might expect for as long as I like with no problem. However whenever I bring up my VPN to work, which uses the Cicso VPN client, it kills the mouse within a few seconds. The cursor moves over to the left hand side of the screen and won't come out. Killing the VPN does not restore function, I have to restart X The VPN concentrator enforces a policy which cuts off local LAN access while the VPN is up. This is annoying, but done for the "right reasons". I have tried both generic nv and Nvidia proprietary drivers, at least 2 different kernels, killing gpm before starting X and there doesn't appear to be any useful information in either /var/log/messages or the Xorg.log. It's an optical PS2 Intellimouse wheel mouse. I'm at a total loss. This doesn't happen on my Gentoo machine, also running KDE, yet it's 100% reproducible under FC4. Does anyone have any ideas ? Please !!! ? ;-) Is it possible that there's some kind of network communications betwen KDE/FC4 and the mouse (which isn't there in Gentoo installations)? If so, is there a way to work around this, or am I going to be unable to use FC4 if I want the VPN ? ANdrew
