--- Comment #6 from Rémi Bernon rbernon@codeweavers.com --- Ah, probably wine is still running in the background, you'd have to kill it first (for instance with `WINEPREFIX=... wineserver -kw`), and then run that command again.
For me the application works fine, on Debian GNOME, and also embeds its icon in the systray if I enable some systray gnome shell extension. There's a couple of issues, as it doesn't react to mouse clicks for instance, but otherwise it is visible.
