I believe the original poster is using Panther on an G4 AGP... which can utilize Tiger. But perhaps he prefers Panther. or perhaps there is economic factors, or like he wrote " for other software compatibility reasons." Just because a computer can use a certain OS doesn't mean you should use it. (such as various people with PC's running Windows XP still instead of the so called latest-greatest Vista) for example my MDD Dual G4 can run Leopard but I choose not to use it as there OS9 apps I still routinely use.
