I got a message indicating a setting has been changed and was asked to restart the IDE. After restarting I seem to have lost the header part of the IDE, also the buttons for compile, and upload are no longer active. The IDE is always full screen and can not be resized. Any Idea how I can reset this…

[image] Xinonix: Any Idea how I can reset this? When this happens to me I find that closing all instances of the IDE (using Alt + F4 on Windows) then opening the IDE again, sometimes multiple times, corrects the IDE setting

Thank you, this solved the issue (changed C:\Users\\.arduinoIDE\settings.json file and modified “custom” to “native”
