Installed Leopard and things worked relatively well. Prompted to update to 10.5.1 and afterwards could not open Stickies. Pop-up window says Stickies don't work with this OS. They worked fine up after Leopard installation and up until this point and I have a lot of important info on them. I've backed up and should be able to retrieve the info and print it if I have to, but I'd like to be able to use them. Anybody else run into this? I'm using a PowerBook G4.
