Hi All, I am bothering by such a function. Any helps on turning it off will be appreciated! The trouble happens when using gnome terminal on FC3, for example, after type in, "cd dir", when I hit Tab key, if there are more than one directory or file named with "dir" at beginning, the screen shakes (or some action like refresh the whole window very quickly) so largely that make me feel very uncomfortable. It won't happen if hit Tab key after first hit, and it didn't happen when I was on FC2 either, any tips on how to let it don't "shake"? Thanks.
