Argh I keep getting an error when trying to upload a screenshot. Both on chrome/firefox.
Here is the dropbox link of the driver info screenshot: https://www.dropbox.com/s/dkgg2wyuiz6rmno/Capture2.JPG?dl=0
As you can see by the colour of the driver info tab.. where as a week or so ago f.lux would correctly disable when using the windows snipping tool, now it actually goes to full dark/late night mode when I use it. So its like the reverse effect. Instead of disabling, it is going stronger in full screen!
EDIT: Ahh that option has indeed fixed it. Thanks so much herf :) I hope this post helps others with the same issue!! Cheers and happy new year
