It's a quirk of Explorer that's been showing up on some people's machines.
No known cause yet, but it gets saved with folder views once it happens.
I've written a script that helps MOST people with the multi-select problem.
It will remove single-select from saved folder views & saved defaults.
Right-click the link below & select 'Save Target As..."

Then extract the contents of the .zip file & run the script.

I have Vista Home Premium with the latest updates. When I want to select two
or more maps (or files) it simply won't happened using the Shift or Ctrl and
the mouse click. Working with, for example, Indesign, itunes or any other
application, it's not a ploblem at all to select more files in one time.
Thank you for any help
