"Group by" greyed out

Hi,

I've installed the latest version of Dopus on my new PC running Windows 7 (32bit). Dopus installed without problems but when
I display my computer folder the option "Group by" under the "View" menu is greyed out. This means all my removable drives
& network drives get mixed in with the rest. I want to get back to showing all my drives in groups. Has anyone any idea what
the problem could be? I also re-loaded my previous backup configuration (where this was working) but it did not resolve the
issue. Is this a problem with Windows 7?

Cheers,
Manuel

Grouping isn't supported yet, though it's definitely on GPSoftware's list.
