I'm using Mac OS 10.8.3. I have a huge display and bad eyes, so I like to have the mouse cursor be the largest possible size. (under System Preferences: Accessibility: Display: Cursor size.
However, I also do a fair amount of video editing, for which I use Final Cut Pro X. Unfortunately, the UI designers who made the Final Cut Pro X interface didn't properly take into account larger cursor sizes, so when I click a button in the program's interface with the "tip" of a large cursor, it won't register. To remedy this, when I'm using Final Cut Pro X, I change the cursor size back to normal.
However, doing this is fairly time consuming, as I have to do it a few times every day. Is there a way to somehow do this automatically?
