Now, it simply does not work. And it's only with FFXI and when using Windower.
Did I *** up a setting by mistake or something? All I've done in the past week is update FFXIV. That's literally it, nothing else modified on my computer.
I barely use any plug ins, and nothing messing with F8 by default. I don't use anything else with the game.
It fixed itself after rebooting my computer once and restarting the game 3 times.
