Run test set from ALM, first test case objects are identified and second test objects are not


WE have automated a .Net application and stored the scripts in ALM. All the objects are in a shared repository and no local objects for any test.

Now when we run two test cases as a set from ALM, first test case loaded the shared OR and execution pass(SWF objects). When second test case execution started it loaded the same shared OR and objects are not identified(identified as window objects).

But if we run second test case alone by assosiating the shared OR, the execution went fine and SWF objects recognized.

Can you please help to resolve this issur?
