I search for an object while the Parent process of the object is busy

I want to search for an object through Test Complete 10 while the Parent process of the object is busy.But test complete is unable to locate the object window during this time.

In my application i am clicking one button that starts a calculation which shows a progress bar dialog.As long as this progress bar is present the application is not accessible by test complete. Now i want to verify whether this progress bar is present or not.

Using FindChild on the parent process is not working . TC is unable to do a Find() on the application as long as it is busy(Shows a rotating mouse pointer). It starts the Find() when the progress bar is finished at which point it just keeps waiting for the progress bar .

Can someone please help me here.
