OK, this is admittedly a silly question that I should know the answer to, but I unfortunately do not. When I was attempting to muddle through the loops in gb last night, I selected one and received the message that I'd need to install this particular loop from the internet or my dvd. The message said that installing the set of loops-which I'm assuming is on the ILife DVD-would take up 1.2 gb of ram. Now that I have my Mac drive split between Windows and Leopard, I would assume that I'd really slow down my system by installing this package. Is it correct to assume that since my hard drive is split, my 2 gb of memory is also split between the two? Thanks for your help. Ginny
