I've had FARR synced via dropbox for probably 8 years? It just means if theres a setting corruption, it's been synced between all my devices. I may just reinstall from scratch and see if that fixes things. Just donated to you btw, I've loved FARR! <3
This behavior always happens, on two computers (admittedly using the same FARR settings synced via dropbox), I've checked the keyboard interface tab - result hot keys are set to Launch.
Tried it with the latest High DPI version. I've tried every perumtation of the Window Options and Launching Files options I can think of. I swear it used to work fine, but I can't remember when it stopped working. Using the portable version.
