https://community.blueprism.com/t5/Product-Forum/Active-Accessibility-Mode/m-p/65563#M18168 I have a web application which launches an iframe popup when the user presses a button. I use AA mode to spy a combo box on the popup.  However, as soon as I've spied the combo box, I try and highlight the element and  I get the following error message "Error - Highlighting results - External AppMan reader thread exited before response from query"   I can't seem to successfully spy the popup elements using AA mode. Any help would be much appreciated.

Make sure you are attached to the correct IE process thread.  To do this you should experiment with TabProcGrowth and Child Index and attaching etc... there is more on that in the Browser Automation Guide and in the knowlegebase.  Also... ensure you are running the correct version of Blue Prism (32/64bit) and running Application Modeller in the correct 32/64/internal/external mode.
