comma key make alt key active
I'm using MacBook Pro (Retina, 15-inch, Mid 2015) with Mojave OSX
Recently weird thing happen, everytime I press comma/double quote keys, alt key become active without I press and it will keep behave like being pressed all the time
This happen when I activated "Enable sticky keys"
When I disable this option, alt key randomly get stuck without even being press at all
How can I fix this problem?
MacBook Pro 15", macOS 10.14
