Sorry Neal - I have a friend with an "e".
I got my copy from the PClinuxOS home page:- http://www.pclinuxos.com/?page_id=188
There's no checksum for the mini version listed there.
I've just checked my live CD, there's no lxsession in the guest account there either.
I tried copying over the folder from my Dell computer which has an older but fully updated version, but as far as I can see the mini version ignores it, seems to be no interaction between the gui you get from the lxdecc and the desktop.conf file. In my Dell changing one affects the other.
There is a desktop.conf in /etc/xdg/lxsession/LXDE, but I'm guessing that's a default not an "active" one.
Maybe I'll get the full version.
We do seem to be getting rather off topic now, which was how to increase the interval between clicks though.
