I'm running into a problem where I'd like to know when a status window is opened/closed and there is no simple way to do that. The on open/close command would be the perfect command for what I need but they don't support status windows.

I personally think it's bad to limit the on open/close like they are. I ran into a problem a while back with opening a query window and on open ? not triggering. There was lots of discussion but nothing came of it.
