Multiple instances are somewhat frowned upon due to the issues surrounding shared preferences, they share on open, but not on changes after that, and on close the last Geany closed gets its prefs saved.
The "open in new window" was intended as a way of getting multiple short term views, that are likely to be closed before the "main" geany is closed. If one of these extra instances is accidentally the last to close, all files open in the main instance are forgotten because the prefs are overwritten with the one file open in the extra instance. -- You are receiving this because you are subscribed to this thread.
