I haven't installed skype, i have downloaded it (static version) untared it and ran ./skype in that folder to use it.
Later when i rebooted the system i got very scary popup message:

The action you requested needds root privileges. Please enter root's password below or click ignore to continiue with your current privileges.

Command: ./skype -session

(below it gave me space to enter passwd, button to remember passwd and below of that regular buttons "ignore", "ok" and "cancel")
Why skype for any reason whatsoever asking me for root privileges?
