AppHang Error on newly-installed MS-Word 2010

I have a new Dell laptop with Windows 7 Home Premium running on it. I installed MS-Office 2010 for few days now. When I started using MS-Word, I am receiving an AppHang error while trying to exit the program. The error is stating: Problem Event Name: AppHangXProcB1 and waiting on Application Name: csrss.exe. Firstly, I don’t have an idea what this problem is all about and secondly, I am using a new laptop and the Office is also newly-installed. How can I fix it?
