DT 3.9.5 & 3.9.6, dragging and dropping email fails

As usual additional information would be useful:

1. What did you drag and where exactly did you drop it? E.g. drag & drop to the Dock icon does not work and never did (due to limitations of the Dock)

2. Is DEVONthink allowed to automate Mail?

3. Does DEVONthink have full disk access?
