I want to reflect an object across a center guide. I select the object, press O for the Reflect tool, but when I ALT click on the center guide, nothing happens. The "target: doesn't appear on the center line and the dialogue box does not come up right away... It does after a minute or so, but without the "target" on the center guide, it won't reflect. What am I doing wrong?
. I'm using CC 2014 1.1 with Win 7 64-bit.
