A Funny Thing Keeps Happening...

Hi Nick,

I haven't been using SUSE for a while, as work has been keeping me fairly occupied, but...

Lately there is something odd happening. A window keeps spawning then closing all by itself; happens
every few minutes, and is gone too fast to even tell what is was.

Is there an easy way to 1)tell what it is? Could it be the firewall reporting a port scan or
something? 2)make it stop?

Hard to tell from where you sit I'm sure, but if you have any ideas I'd be very grateful.

I have run top but did not see anything too scary...

Thanks.

Dan.
