Also, check the debug output window when the exception occurs.
Most likely, you get a 0xC0000005 First Chance Execption - e.g.
Access Violation. If you set 0xC0000005 to Stop Always as Simon
suggested, you'll be able to see the (assembly) code where the
exception is thrown. Hopefully, you know x86 assembly and can
make sense of it...
