Hi everyone, I’m using flame 2025.2.2 I want to compare the primary and secondary layers using scroll lock and print screen. They don’t work for some reason. This use to work in previous versions. Any idea why? It’s a bit of a pain when showing the before and after to clients. Thanks for any info in advance. Cheers Deepak ---

I’ve had something like this on a Mac before @Deepakpais Are you using Mac? > [@Problem with F13 F14 F15 keys on Mac using PC keyboard](https://forum.logik.tv/t/problem-with-f13-f14-f15-keys-on-mac-using-pc-keyboard/5052/2): > > @PlaceYourBetts that keyboard in Flame doesnt really do what you think it does. If I were a betting man, I’d bet that at the OS level on the Mac side your F13 and F14 are set to something stupid, like Display Brightness Increase and Decrease, respectively. Head on over to System Preferences, Keyboard, Display, and make sure the Decrease display brightness and Increase display brightness are disabled. Most of the time these things happen its a conflict at the OS level. ---
