Sounds like you've got the single-select bug...
There's a flag that tells explorer to only allow one item to be selected at
a time. It's used in the display of the file open/save dialogs. Sometimes
it somehow creeps into folder views and the result is what you describe.

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.
