What mouse do you use for photoshop on a mac.
I only have a Magic Mouse and this thing seems to be all over the shop when trying to use it in photoshop.
I seem to just touch it somewhere and it's like its got a mind of its own.
Download MagicPrefs and restrict the scrolling area (Configure Scrolling button at the bottom) to a narrow vertical strip where the scroll wheel is normally located. Your mouse will be far more usable.
