As noted in my earlier post and comments, my tablet laptop and its pen occasionally lose touch with each other. This happened again today.
Instead of rebooting, this time I just closed the laptop lid and let it hibernate. I then opened the lid and woke the laptop again. The pen started working again. Amazing.
That reminds me about the joke about what you should do when the car won’t start. The “IT-expert suggestion” is to get out of the car, get back into the car, and then try again!
Now if you are in the middle of a Camtasia recording, this could still be a problem. I don’t know what happens if you try to make the laptop hibernate while recording. Perhaps it would be safest to use the trackpad (or the emergency mouse you brought along) to stop the recording before making the laptop hibernate.
