I don't know about other programs but definitely not with Pegasus Mail. As already determined, some of its windows will maintain their moved location, some won't.
If you are running it on a second monitor just so you can keep an eye on it, there are numerous ways to have it run minimized and be alerted of newly arrived messages (eg: an animated tray icon, a telltale window, a popup notification triggered by a filter). I say this in a final attempt to save you some grief should you ever be in a situation where you need to run Pegasus Mail on a single monitor. It will startup, but you won't see it because its main window will be offscreen, at coordinates where a second monitor once was.
