Horizontal Scroll In Word Press Overrides OS X Defaults

I have previously mentioned that the WP editor is subject to very poor horizontal scrolling. In nearly all my implementations, the horizontal scrolling causes very bad anomalies to happen in the native editor for pages and posts. This is particularly a problem on the Magic Mouse, by Apple, that allows the finger to do scrolling or other gestures. Some have suggested that plugin’s cause this, but I’m very skeptical of that, seeing that I’m experiencing the phenomena in dozens of sites, each of which have different combinations of plugins. And by the way, why would a plugin change the native WP Editor in ANY way?

To combat this issue, one can go to the Apple System Preferences and disable scrolling in the Accessibility settings. But the real culprit in the horizontal scrolling, and alas, Apple does not give that fine tuned control. I turned the scrolling off, and this did solve the problem.

I researched on line how you can disable JUST the horizontal control, and there is a terminal command that does this:

defaults write com.apple.driver.AppleBluetoothMultitouch.mouse MouseHorizontalScroll -bool NO

This works in ALL applications EXCEPT WordPress. Apparently, WP ignores the settings in native OS X and continues the poor horizontal scrolling. This was surprising to me.

My fix right now, since I also use a trackpad, is to allow the Magic Mouse and Trackpad to work together. However, the Magic Mouse has all scrolling turned off, while the Trackpad has it turned on.

Hopefully this will get some attention at the WP Dev level.
