Well...,the window is modal dialog which that blocks input to other windows means if that window is open you can't type/click anything on your tested application's window.the window asking me to stop specific service and only then it will be able to move on.
what is happening in during the test run when this window display is that i can see TC is looking for required object that cannot be found because it's blocked by the interrupted window.
i solved that issue by stopping and starting the service behind scene so this windows doesn't appear any more but better to understand why the window cannot be closed although TC was set to close overlapping windows.
Thanks
