P.Walker Stuck stick

[peroncho]

Game runs perfect, but when i set the trieanfle, X, circle, square to the right stick, it gets stuck to the left wehn i move the stick to the left, not happening with the other directions, and when im aiming, its the same when i move it up or left, its like that until i move it to another direction :/
Tried it with the latest version and with "ppsspp-v0.8.1-677-ge978b08-windows-amd64" too....it keeps happening, i cant play it unless i use the buttons to move the camera, which is pretty much unplayable too...

...any idea?
[already tried unchecking keyboard and 360, and mapping the pad on the keyboard section only...but nothing]
