Since yesterday’s update, the contextual menu entry Analyse ? doesn’t work (never had this issue before). The analysis doesn’t launch and the notification doesn’t appear. I just wonder how to solve this ?

nothing at all
No, I tried that before posting yesterday 
Seems we will just have to wait for a fix, and trust our email provider’s anti virus.
