Running LR 3.4.1 on Win 7 64bit, Intel i7 960 4x3.2ghz, 16gb RAM, dual monitor, nothing else running (except task manager and explorer windows, even disabled Norton) editing JPGs from Canon Rebel XTi. Since the performance was "sluggish" during prior LR versions I built an entirely new system - yet this problem still exists!
I am not the only one with this issue... but I don't understand why everyone doesn't have this issue?! How can or Professional Photographer use even LR?
