@ThereseSolimenoit used to work fine. Clicking X always closed everything on my side. I'm trying to nail down what has changed. If I want to hide it from taskbar and leave it running, minimizing to tray is the way to go for all softwares since forever. Is MS trying to force me to leave it open by adding complexity on the close process ? Or is it a bug in my installation ? The setting is not doing what it should.
