Is there some additional logging I can provide that would help develop another patch for testing?
No, I have everything I need, including the knowledge what the problem is. Now I just need more free time to work on this.
Basically to solve the problem we need to avoid sending WM_MDIACTIVATE message twice to a being activated MDI child.
