Hi @junkman
Thank you for sharing all the details about FxSound behaviour that you have observed. One of the differences in our setups is that we are testing on Windows 11 and you have Windows 10 Pro 22H2. I will analyse and find out the reasons due to which the system tray icon of the application can get hidden, and get back.
Thank you for the update.
We are glad to hear that the issue is resolved.
Anyway I will keep an eye on this issue and debug it if I ever encounter it.
