With my Mac (OS 10.9.3) scrolling the editor with my Magic Mouse is a pain. Using the swipe gesture to scroll up or down makes the text jump around like crazy. No smooth scrolling at all, impossible to use. I ended up actually grabbing the scrollbar, pulling up and down like its 1999. Arduino IDE is version 1.0.5.
Seems to me, the UI is set up for Windows-like mouses with scrollwheels, moving three lines or so with every step of the wheel.
Anyone else or is it just me?
