Ok odd one here.
Our SENCO reported that she couldn't add medical notes to a student record although according to her permissions she should be able to.

I watched her and from the student overview she clicked the 'Links' link to be taken to the detailed record and indeed she couldn't add medical notes ('add' button is greyed out).

However, once she clicked the drop down on 'Links' link and selected the 'Student Details' link, she could add medical notes!

Any ideas why she gets different permissions depending on how she gets to the record?
