2. Lanux -- in your original post you say you end up with 2 instances in tray. Can I ask you to elaborate? Do you end up with 2 separate copies of the program running? Or just 2 system tray icons?
-mouser
i get two separate copies as can be seen in this screenshot below.

3. Lanux, can you see if the same behavior happens if you EXIT all running instances, and then start them both up (let the first fully start before launching second) with your new shortcut?
-mouser
the behaviour persists even after exiting both instances and re-starting again.
by any chance, does SC have any option like the one in the image below, which i may have inadvertently turned it off/on?
