Touchscreen gestures are not working anymore.

Hi there. I used to work flowlessly with the touchscreen gestures and stylus on my Lenovo Yoga 530, but today I realized the first moment that these amazingly useful feature does not work anymore. I mean, it's of really heavy importance that this bug is fixed soon, it's literally a feature every other image software optimized for toichscreen can do easily. 

It's just the way it is supodes to work, completly intuitive. And i0ve been messing around preference's check boxes, and I'm pretty sure the Active gestures box is cheked. But for my misfortune it isn't working as intended.

Please, plase, help me get back the comfiness of enjoying work.
