If this app is giving you any problems, you need to suspect that something else on your Mac is causing a conflict. Installation/configuration was a breeze for me, and it always performs flawlessly.

IMHO, Skype has everything that we expect from any Mac application -- an attractive interface that is intuitive and easy to use. Seamlessly accesses and dials all the telephone numbers stored in 'Address Book' -- and if your local telco charges like a wounded bull for international calls (like Australia's Tel$tra), then Skype's prepaid international call rates which are typically around 2.7 cents per minute should be enough to put a smile on anyone's face :-)

Definitely on my 'can't-do-without' list.
