Behaviour of systray icon

Hello,
my question does not concern a real problem with Comodo (with whom I’ve rapidly fallen in love :smiley: ) but with the systray icon management: I’m running Windows XP SP2 and the systray icons are configured in such a way that the inactive ones stay hidden (I’ve checked this option from the Start menu dialog).
Well, Comodo’s icon is hidden from the start of my pc, although I know the firewall is active, both from the Task Manager list and from launching applications which are on an “ask” basis: why then does the icon disappear ? (I must add that clicking on the systray arrow that shows all icons, Comodo’s is there, bigger than life :wink: )
Just curious …
Thanks people - and keep up the good work !! (:CLP)
