Something I noticed and I'm not sure if it is something related to EverythingInterface or some Windows behavior, so I just want to ask here first.
When EV is not running and I use EverythingInterface.start() in a FAYT script, the FAYT field will loses focus and close. It seems to be because EV's icon in the system tray gains focus.
However, when starting EV regularly, using with the -startup argument, that doesn't happen (its icon in the tray area doesn't gain focus). I confirmed this with an AHK script that logs focus changes.
