>I don't see a corresponding event that fires when the container deactivates.

UIEnable handles both the enable and disable. It passes a parameter telling you if its going or coming (goes against the rest of the event model, but hey)

>It also doesn't fire the first time the page is activated if it happens as a result of the form's initial activation.

True, but easy to fix (my pageframe does a UIEnable on the first page at startup anyway)
