Multiple file selection (Ctrl-a, shift, ctrl, drag) broken in Vista

Sometimes multiple file selection is broken in Windows Vista. Dragging a box around folders and such, multiple selection with Ctrl or Shift, or even Ctrl-A won't work inside folders (although they may work in the drive view (my computer) or on the Desktop.

For some reason, Explorer saves "single select" to folder views and saved defaults.

I've stumbled across a script that fixes this without too much work:

The script seems to work quite well. I ran it, logged off, logged on and multiple selection worked perfectly :-). Thanks go to Keith Miller.
