When I try to edit my webpages with contribute I can't do so
with some pages: when I click the Edit-Button, Contribute starts to
work but after a moment it goes back to the normal screen and
doesn't offer any edit-functions. It looks just like I haven't
clicked the edit-button.
The page itself was created with dreamweaver and has editable
regions. From about 20 pages that derive all from the same
Dreamweaver template I can edit about half of them, the rest
behaves in the described way.
