Hi Ellen,

The Dim checkbox in the bottom right is purely an editing function. The link below will take you to an answer I gave a short while ago on the same topic.


Any further queries, just get back to me here.

Hi Ellen,

As Ned pointed out, the Dim check box is a design time function only, designed to help you see what is on a layer during development.

What you want to do is easily accomplished with a shape though. All you need to do is add a shape as the first layer, set your color and opacity as desired, and now you have the same effect, only now you can adjust it as much as you desire. See my attached example.
