Rule window clears input while typing

When I try to type a rule in the rule box for a prototype in the Information window, or try to edit a rule, suddenly all the input will be cleared making it impossible to use. I got a rule in once.

No problem if I display the rule attribute in the attributes list for a prototype and enter the rule there, even though I cannot see it. I’d prefer to use the inspector rule tab.

Not sure how to fix this.

You have an agent that is forcing a screen refresh as you type. You can resolve for now this by turning off automatic agent updates.

Thank you! I would have never figured this out.
