Click to Commit or Pull and if you don't exactly click on the icon, it feels like sourcetree is unresponsive as it is a dead click. If you click on the words "Commit, or "Pull" nothing happens. You have to click exactly on the icon itself or it won't register. 

This is a horrible experience as too often it feels like sourcetree is unresponsive or hung when I click on the icon surface to do anything.

Expected:
When I click on anywhere in the button surface, it should register as a click.
