@herf Thank You.

About your note - why dump something just because it's old if it works fine for most things.

I exactly have the same problem.

Sadly that program doesn't suit my needs and so does f.lux if it can't completely ignore my second monitor. :(

Thanks @Paul-Harris - for some context, f.lux v4 avoids constantly looking for color changes and tries only to "fix" what other programs do in a few specific ways, so you're seeing what's expected, except that f.lux should definitely be detecting any new screen that makes your desktop bigger, so that's a bug.

That list currently includes: plugging in a new device (which seems like it's not working here), returning from sleep, and switching apps (like alt-tab).

When you plugin a device, does it look right for a bit and then reset later? Or does the tint instantly disappear?

Thanks for this, i wouldn't expect this to be the case either, the software is only installed on 3 machines. Mine (never rebooted) and two others that are rebooted perhaps twice per day maybe 3 at most!
I will have a look and see if anything comes up. It certainly didn't seem right to me, maybe it is a bug on sophos!

@TwoCables
Thanks. This worked great.

Until Microsoft announces that they're dropping support for 32-bit programs, f.lux will remain 32-bit in Windows. After all, what sense would it make to create a 64-bit version of a teeny tiny little program like this when there's no need to do it?

@TwoCables Well, pray tell how to find useful info? Tnx

Can you fix your screenshot?

Try uninstalling it and re-installing it and then restarting the computer.

Also, I think you have to make sure Windows Night Light isn't enabled.
