I've upgraded to 10.4.8 recently from 10.3.9 and am having big hesitations/delays in all apps that I use. I've upgraded 2 separate machines so I'm pretty sure it's not something to do with an individual system, seems like a Tiger issue. Double clicks take a few seconds or more to start, opening things, maneuvering through windows/pallets (layers, etc.) in apps is super slow. I'm using CS2 and having issues in all apps within it as well as other software. I have a G4 867 dual MDD with plenty of RAM and HD space and a G4 733 Quicksilver with plenty of RAM and HD space as well, same symptoms on both. My laptop (G4 FW800) running OS 10.3.9 is quick as these used to be. Anyone else have this prob? Any ideas how to remedy? I'm stumped.. Thanks much for any help.
