I use an old iBook G3 (!) for watching videos, a little surfing and sometimes skyping. When I launched Skype recently, the program started, and as the contacts appeared, a window came up that said: "A new version of Skype is now available, 18.104.22.1682, which you must download and install if you want to continue using Skype", or something like that. This had also happened on my main Mac, and when I downloaded it had bugs. Nevertheless, once I had installed the new program, I was able to use one of the old ones on the newer Mac. However, this new program does not run on PPCs, one can download it but not install it, which means that, effectively, one cannot use Skype on PPCs anymore. Any thoughts/solutions?
