Yeah dude, I know usability will be super low on any list, it always is :(

I didn't notice it until you pointed it out, and the indication from other people I've played with is the same.

It still seems like it's a usability issue if it's something that needs to be pointed out and is not intuitive.

Which is why I put [usability] in the title, the people who prioritise the issues know what kind of issue it will be.

With that, I'm going to edit the issue with my above comments.

Are you launching from Steam? If you are, steam has it's own hotkey for screenshots which is f12 I think (I've changed mine).

Using FRAPS allows me to use the Printscreen key (kind of annoying, but it auto saves every screenshot I take. There are probably other screenshot applications our there.

Added some screenshots for you
&
steps to reproduce:

1. select to Inspect book on inventory screen or when looking at it

When I was playing with other people, one had a head torch and the exact same thing was happening.

Can confirm this,
Steps to repro:

1. Join a night server
2. Enter a building
3. either have a head torch or flashlight & turn on
4. you can see beam through the wall

I've seen it too, over on the east coast next to a lighthouse.
