Hi xx97
I hope you are keeping well.
We have the following video guide on Dealing With Unexpected Pop Ups which goes over the steps to implement this.
I've set up the OnUnexpectedWindow and similar to your steps its ;
1. Record a keyword test to handle / interact with the pop up window.
2. Add an event control for OnUnexpectedWindow
3. Add keyword test under OnUnexpectedWindow script.
When running the Keyword Test and if a pop up window occurs the OnUnexpectedWindow handler will run the keyword script to handle/interact with the pop-up.
Does the Event Handler / OnUnexpectedWindow handle your pop-up?
Please let me know if the video helps resolve your query or if you have any additional questions.
Thanks,
Shane
