Using Intellij 15.0.3 on Mac OS 10.11.2.
When I have a code tab open and it's long enough to need a vertical scroll bar, but not wide enough to need a horizontal scroll bar, the editor will scroll up and down if I run my finger across my magic mouse side to side.
In my opinion, this is unintended behavior. In other apps, such as Sublime Text 3 in the same scenario, swiping my finger side to side on my magic mouse will do nothing. The document will still scroll up and down as intended when swiping my finger up and down on the mouse.
Is there a way to disable the vertical scrolling fallback if the document isn't wide enough to scroll side to side?
