Hi Remoc,
Thanks for your answer. Still the only program I can act on is <Limewire setup wizard> in which I do not see any [Tools > Options > System Tray] menu item. I have no access to Limewire PRO program - this is my problem.
By the way, I might have not understood your suggestion. Should I look for [Tools > Options > System Tray] in the MS Windows configuration panel ?
Thanks for your help
