Using Wincompose 0.9.4 on Windows 10 Pro 64b 1903:

Came here via ticket #35 since the described behaviour is similar to what I'm observing. But the ticket is quite old, closed and after all slightly different and it seems not to exist a current issue on this, so I open a new one.

My PC is usually continuously in operation, Wincompose autostarts with a reboot and runs smoothly. But every other 2~4 days (no excact timekeeping), Wincompose just ceases to operate and the icon disappears from the system tray. It is no problem to restart via start menu …

… which also brings back the icon to the systrem tray:

Everything then works again, but this behaviour ist quite annoying. Is this known and under investigation?

I also noticed that when restarting from start menu as described the UAC dialog doesn't announce Wincompose but the configuration tool for task scheduler:

Does that give hints?

Bye
