help please! (vista) my control panel, when i try to open it, merely flashes for a split second and then nothing. at first it appeared blank, but now its even worse. i have tried the solution of manually deleting then replacing the .cpl files within the system32 folder, but theres so damn many of them. surely this is not the most straightforward answer. or if it is, then which particular .cpl files are causing the problems? is there any other way to do this? cheers.
