Using dockManager on control stops _Load event

I'm not sure what could cause the Load event not to fire. We don't do anything to try and block it (I wouldn't even know how to do that). I know of other customers who have done a DockManager within a tool window of another DockManager though.

The UserControl is added to the Main form's dockManager programatically, not at design time. The UserControl is actually passed to the main from a dll. Do you know of anyone having success in this situation?

I'm not sure as to the specifics of how they did it but I know I've gotten email in the past from one or two customers who were using a DockManager within another DockManager's tool window.

This is something I've done, and there really weren't any tricks. I have DockManager controlling my main application, and I also have a DocumentWindow that gets loaded which also houses a DockManager control. I've done everything programmatically (other than adding the main DockManager control). All this code resides in the same DLL, but I can't see why that would matter.
