I am not sure if this is a KDE thing or X or something else.

I am running KDE 4.2.96 but this has happened for a long time prior.
Hardware is a Dell Optiplex 755 with built in intel graphics

Every now and then my cursor will just jump up to a corner of the screen.
It isn't always the same corner either.
Just kind of odd and irritating.

Also randomly my F-lock and Num Lock locks turn off on their own.
I see them flash and turn off randomly.
This is on a MS Natural keyboard.

Anyone else experiencing anything like this?

Thanks
