Thanks for the quick reply, as you can see in the bottom right screen. You can see the SP version. Everything is up to date. i changed the setting temp protection to "Don't show" an back to "show message" no result. I also changes the time the messages show in different value's 1s to 1.5s and so on. When i vape, without the pc attached. The Therion stops at the regulated temperature but no message. (i hope you understand my dutch Englisch)
