I am using the same keyboard for Linux and Windows. I disabled the Keylock for both OS, by rolling a piece of metal under the key. Nothing visible. Case solved.
Could have changed it in Linux but the others OS is for work and I can't install or modify anything on that computer.
Funny, I never would have the idea of buying a tent to leave it on the field after a festival. Even a cheap one. I had a similar feeling the first time a saw a disposable camera. Leave me now, I need to sit and reflect on the meaning of life.
I would expect a alien calendar to be as complicated as ours. The calendar we use is the result of a long and rich history. Their would likely be as complicated, especially if there are part of a tree sun's system.
