It might help if you let us know what language was used to create your tested application and how exactly problematic window is opened (and why are you talking about two different applications - is this window provided by some other application?), but maybe this help topic will provide you with some ideas: https://support.smartbear.com/testcomplete/docs/scripting/calling-methods-asynchrounously.html
Hi,
This is an desktop application developed by C# language and its completely one application if we click on pop-up button a new window will open with complete details of that applicant.
