Tracing MFC message handling

Question

Trying to upgrade an MFC app to use the new MFC feature pack, we are loosing the messages from a context menu. The menu appears and can be clicked, but the message seems not to be handled anywhere. We overrode OnCmdMsg() in lots of places but to no avail, the context menu's command message are not caught.

Is there a way, tool, or approach to trace messages?
Any other ideas how to solve this problem?

Try SPY++

Provides a graphical view of the processes, threads, windows, and window messages of a system. For more information, click Help in the tool.
