I'm not having this problem with any other CS5 apps so far. But whenever I'm resizing or dragging objects within Indesign CS5, the resizing lags by like a second or two. Thinking CS5 is now 64-bit, I thought it would be faster rather than slower? I'm using a 2 Ghz Macbook with Intel Core 2 Duo and 2Gigs of Ram. EDIT: Processor is indeed Intel Core 2 Duo and not Intel Duo Core, my mistake.
