Thanks - that worked. Took me a while to find that option though.
All I need to know now is why Vista keeps deciding to change this setting. "
I need to do it again - and just can't find the grouping option. Anyone know where I might have found it before?
I expected to see it on one of the Folder Options panes but just can't locate the right one.
Edit Never mind. Found it.

Just in case I (or anyone else

) has the same problem in future, here's how.
Organize->Layout-> then make sure Menu Bar is ticked (it wasn't on mine)
From the Menu Bar choose View->Group By->(None)
Easy isn't it.
