After running through a painful message debugging session today, I realised again that at the top of my debug tool wishlist tool is MsgMon, a “Procmon for messages”. Spy++ and Winspector Spy are just not up to the task. Once you start using Procmon, with its caching of call stacks, filtering, phenomenal performance and more, life seems very hard each time you start Spy++.

I would love to write this tool, if only I had the time… It would be nice to be able to use the existing Procmon framework as it is so solid…
