In XP I could navigate around an explorer window full of files with the arrow keys or by typing the beginning of the file name and it was more or less instantaneous. In Win7 there's a several second lag that seriously slows down my productivity. Similar when dragging folders. I suspect Win7 is scanning files as they are selected to enrich the UI somehow. There has to be a way to turn this "feature" off and speed things up. I tried turning off Aero, turning off some of the panes etc but no good. HELP! My system has 6gb ram, a core duo cpu, is Win 7 Pro 64 bit, 7600gt video card, and it's a fresh install.
