When I play ppd, the joysticks of my DS4 (and DS3 too) doesn't work and also the macros I set with DS4 windows are completely ignored by ppd.
How can I fix that?

Until this is fixed, I guess a workaround is to use JoyToKey and set the Joysticks to the keyboard binds you set for the L and R buttons or whatever buttons you want it to be set to.
