No I refer to :
http://drupal.org/project/Views , details for release 6.x-2.8 , bug fixes section :
#622602: Missing ORDER BY in some views with tables due to incorrect test for default table sorting.

The view proposed in Website is : http://www.lamurithienne.ch/collection is not working. When clicking on column header, we cannot change the sorting order.
This was working in version 6.x-2.6, incorrect in version 6.x-2.7 and still incorrect in 6.x-2.8

It's not working for all the 4 columns which are cck Fields. It's a view field.
What do you think?

I solved my problem when I removed a sort criteria that was setteld in general sort criteria section.
When I created first that view, I put there a sort criteria on year. Then later, I created a table view with sortable fields and I never removed the general sort criteria. It was working fine. Since view 6.x-2.7, it was not working.
So I cleaned my view and it's OK now.
All the best
