@herf - I have been using this app since some time now. I just want to "Thank You" people for developing this app. Its the best Light-Filter app. :)

@herf (the simpler solution is probably indeed to allow the settings to go lower. People with a low-quality screen will see by themselves down to what level they can go for it to be contrasted enough)

@Reycko if you look in f.lux options, is the "Software mouse cursor..." option checked? If so, try unchecking it.

@Darba I'm sorry it's not possible. There's nothing in the Registry for it.

Some advanced users might want to tell me that it might be possible with AutoHotKey and I wouldn't be a bit surprised with all that it can do, but I wouldn't know how to do it. So, I recommend asking the AutoHotKey communities, including the one on Reddit.

@GrrPcNotWorking no other reports like this yet.

If f.lux is not running (like safe mode) I would not expect it's related to a crash.

@anderk the keys supported are alt+PgUp and alt+PgDn - we also have an option to turn on "surface keys" for Microsoft surface keyboards when the function lock is on.

@ZezFz our rule of thumb is: if you are bringing the software to work, it's personal use. If the employer (or IT) is involved, it's commercial.
