FAH v8.4.2 on Windows, System Tray icon disappeared allowing second instance

[Hou5e]

With FAH v8.4.2 on Win10, the Windows System Tray notify icon for FAH was gone (it ran for a week and died at some point in the last few days with no pop-up error messages), so I started FAH up again, only to find I had 2 copies running with Task Manager (there is only 1 GPU on this PC):

Since the system tray program wasn't running, FAH didn't prevent multiple instances from being run. When FAH started up the second copy it should probably check if it is already running and try to prevent that (even if it's a message that says FAH is already running, do you want to continue to run another copy).

v7 solved this by taking an exclusive lock on the client DB. I'll add this to v8.

Fixed in v8.4.4.

Are you sure the systray icon was really gone when you ran the second F@H instance? On Windows, sometimes the systray icons will be hidden by the OS and you have to click the up chevron icon to see the hidden icons.

Perhaps you know this already. I'm just trying to eliminate explanations for the disappearing systray icon.
