I have Windows 7 HP x64 (from two different DVDs) on both my PC and one of my laptops. On the PC I can select 'Group by' for a folder, when I right-click, in all folders. On the laptop though many folders have this option greyed out (though not all): for instance I like this option (by date) for the recent folder (C:\Users\Martin\AppData\Roaming\Microsoft\Windows\Recent). OK on the PC, greyed out on the laptop.
Anyone know why? Thanks,
