What steps will reproduce the problem?
1. Right click on map and create a new note.
2. Select the box on the right to change the icon using the icon library.
3. Select an icon such as the money bag.

What is the expected output? What do you see instead?

I expected to see the new icon in the box. Instead, I got the error message and I'm unable to select an alternative icon from the library.

What version of the product are you using?

Version 6.02.4000

Do you have an error log of what happened?
