Whenever i pick the scale tool and click on a selected region, the scale tool defaults to "dont preserve aspect ratio". If I jerk the mouse slightly when I first click on the selection with the scale tool, it usually warps a little bit. So every time I use it, I have to be extra careful to apply my first click without moving the mouse at all. It gets old, fast. How can I make sure that the scale tool starts off with preserve aspect ratio right off the bat?
Set the option in the Scale tool, then go to
Edit>Preferences>Tool options and click
Save tools options now.
Warning: Of course this saves all the options of all the tools, plus the current colors, pattern, gradient, brush, dynamics, so make sure everything is as you want it before clicking.
