New Post: Debugging hangs if an event handler for a UI element is set and event handler gets executed (V8)

Hi again,

With your application in the hung state, try attaching the Visual Studio debugger (Debug -> Attach to Process), selecting both Native and Managed (v4.x) debugging modes. With Visual Studio attached, click "Debug -> Break All" and use the Threads and Call Stack windows to find the relevant stack.

Good luck!
