The Email scanner also appeared stuck it was just sitting in the tray(I use outlook 6) and the live update was stuck on 3hrs even though I had just manually updated.
And I could not turn off the silent mode Via the tray icon or the main GUI??
I did a restart and all appears to be working now,I have the update 16.5.0.134. Should I be worried or just dismiss as a one off?
Thanks for any ideas on this.
