Notes:
The MSDN documentation states:
When you use a Win32 API that has a callback in managed code, such as SetWinEventHook, you should use GCHandle class structure to avoid exceptions.
This is apparently not accurate as the P/Invoke layer automatically generates a marshaling stub at a fixed address:

Alternative Managed API:
The ManagedWindowsApi project (http://mwinapi.sourceforge.net) provides a SystemAccessibleObject class to access accessible objects and handle accessible events.
