WPF Container application crashing while recording.

Hi,

I am working on a WPF container application. I am scripting using DP and whenever I spy the objects on the application, the application is crashing. Also sometimes both QTP and application is crashing.

Later once I launch the application, QTP is not able to identify the objects, it is identifying as WinObjects.

Please help!!!

Thanks,
