We have a tree structure in our application. When I record and play a test, the test gets passed. But if I restarts my virtual machine and attempt to run the same test, the tool fails to identify the tree structure. In the test results, I encounter the 'treeList object does not exist' error. Additionally when I check the "Show in Object Browser" option, it displaying an error stating 'Unable to highlight this object, because it does not exist' error. Nevertheless, when I create a new test using the record option, it plays successfully and passes. In the Name Mapping, I notice the creation of a new wndafx object with different wnd class values like wndafx1. Old - wndafx (wnd class- Afx:00090000:8*) New - wndafx1 (wnd class- Afx:00F80000:8*) Like these, its creating on every instances. Can you please advise on how to handle these dynamically changing class values? Thanks, Charlz Solved
