Any advice would be helpful.
I have a G4 Powerbook, PPC , and loaded leopard onto it so I could use my new
itouch.
It sincs great, and all of my photos went to the itouch, but when I went to try to edit my photo folders in iphoto , I keep getting the "quit unexpectedly" message and now I also find that
when I try to do a software update, explorer also wont work then either.

Did I do something wrong, or is it an incompatibility with my older system?

Any help would be appreciated,

Thank you
