Scrolling inverted in Blueprint Editor OS X 10.10 / UE 4.7.3

Hello pizthewiz,

After some testing I was able to confirm what you are reporting. Unfortunately this is not a bug, but just the use of the “Natural” setting. Simply disable this option and your scrolling should function normally while in the editor.

Let me know if you have any questions or need additional assistance.

Cheers,
