I am running into a strange problem. After a few minutes of using Chrome or Firefox, two finger scrolling on my trackpad stops working on these applications.
Every time I restart these applications two finger scrolling scrolling works again, but then after a few minutes, it stops working. All my other gestures work fine (one, three and four finger movements) except two-finger scrolling.
I have no idea what is causing this. I haven't had this problem before until today.
I am working on the latest version of Mavericks on the latest MacBook Pro.
