Nearly 60% CPU usage by FT from my 2010 MBA. This is much higher than on 10.6.7 when it was (IMO, still high, but) "only" 30% or so. Also kicks the fan up to ~ 4200 RPM, or more than twice its normal speed. Have you installed 10.6.8 and noticed FT tearing up the CPU usage charts on Activity Monitor? I use FT for collaborating with remote co-workers and sucks having this machine buckled over form the load of one app. SMH.
