[LAU] qjackctl: disable baloon popups?

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 this is something that has annoyed me endlessly for years, and i still haven't found a solution. the issue is minor (that's why i haven't asked before), but annoying nevertheless. so: i'm using qjackctl with the "system tray icon" enabled. when i close the application window, qjackctl keeps running and is accessible via the system tray. cool. that's what i want. however, every single time i close the main qjackctl window, a balloon pops up in my notification area, telling me that the "program will keep running in the system tray" and how to really shut it down. the first time i read this, this information was informative (i suppose, it has been years). but no longer. i already know that the program will keep running. that's why i'm using the system tray. there's no need to tell me again and again (even within a single session!). there *must* be simple way to "not show this message again", without completely disabling tray notifications. but how? btw, this is on Debian/sid with xfce4. fgasdmr IOhannes
