I noticed this a few days ago. I take photos at work of by backroom stock, then go out to the sales floor to see if I need to pull any of that stock. I use screen write to take notes on the photos as to what I need. It works great..... except during an 10 hour shift I had to do 3 reboot because screen write stopped working... in fact all the gallery option stopped working. Kind of annoying, thought it was just me.
Seemed to work well for a while, then I would get interrupted, and walk away from the project for a few minutes... then I would go back and it wouldn't work.
