When I click an object, there's no border around it

When an object is clicked it usually highlights it with a blue border but for some reason that's not happening anymore. The weirdest thing is that it's only not working on one specific layout, it works fine on other layouts.

I'm pretty sure I just pushed a button or something by accident, but if it helps I have the most recent patch that came out earlier today.

You are a lot more experienced with C2 than I am, but that happened to me when a layer was locked. Could that be the case here?

Or maybe you simply have the wrong layer selected in the layout.

It's hard to tell without seeing the file.

I hope that helps!
