Hi everyone, I bought my first uMbp the day Snow Leopard came out. Unfortunately, it was not installed on the uMbp. So upon running the mbp for the first time, I proceeded to install SL. Now occasionally, maybe a once every other day, whenever I open up a few applications like Word or maybe even a new tab in Firefox, everything would freeze and the spinning color wheel would spin for about 30 or so seconds and everything would resume to normal. Now I ask, is this normal behavior? I have the 2.26ghz uMBP edition with 2gb of ram. Should I go ahead and do a clean re-install? Someone shed some light.
