Print screen key is not working on certain applications

Question

First, let's say I've already read this question and this one as well with no luck for me.

I've got Lightshot installed and with the Print Screen key mapped, so every time I press that key it simply grays the screen in order to select the zone I want to capture. It works fine on Windows explorer and mostly every single program (Windows 10 Pro running).

Problem comes when I want to capture Visual Studio 2017 or the program I'm actually developing.

Since I'm a developer, I know when and how I'm capturing key events through my code and I know right I'm not capturing at any time the Print Screen key.

I thought it might be a problem related with Lightshot itself but seem it isn't, since I press the Print Screen key and it effectively performs a screenshot, but not through Lightshot.

This lead me to guess which program could be actually capturing the event, with no luck. I was curious about the Dropbox issue, but I haven't even got the Dropbox client installed.

Any thoughts?

Solution

I've got this finally working and it's related with the administrator privileges my Visual Studio was running in.

I fixed it applying this solution closing Lightshot and opening it again.
