Skype Crashes on Powebook G4 OSX 10.5

Skype & isight both are unresponsive and crash upon opening. Anybody have any suggestions?

Things I've tried:

repairing permissions
reinstalling skype & isight
reinstalling 4 previous versions of skype
Logging in as different user
deleting skype & isight preferences

Thanks,
Amy

Hi Amy, Welcome to the Forum. Try using Appcleaner to remove all current Skype stuff and downloading an even older version and starting again. Had the same issue recently putting Skype on a G3. Look here at third posting down;
