I have a strange issue with Documents libraries in SharePoint Server 2010.
In all of them I couldn't edit doucment or add new(upload is available, edit properties also)

I use administrator account with full control permissions.
All libraries inherit permissions from parent site.
Other lists works fine.

Where is the problem?
Thanks in advance, Chris
