using Skype

[GNV]

I use Skype without problem on my G4 laptop.  However on a Quicksilver Mac, 10.3.9, upgraded to a G4, Skype 2.7 crashes, and Skype 2.0.0.6 just doesn't seem to go anywhere, although it doesn't crash. It doesn't seem to dial when I tell it to, and doesn't allow me to cancel/hang up in normal fashion.  Any advice?  Thanks.
