On my linux box, every time I select a thread, or start a new entry etc, I see that one or many cookies are sent.

On a terminal, I get the message

Received unknown cookie "CalciumDisplayParams"

Now I do have a perl script called Calcium, (Calendar viewed through the browser) but it's definately not running now, not in any browser window, and in any case why should an action of ELOG trigger this?  I realise it may be due to an idiocyncratic set up of this box.  But in normal operation, I doubt the user would see these cookies being received.
