Hi,
Your English is fine!
I see similar behavior. I normally have Organizer open. If I then open Navigator, I am prompted to save changes on exit. I have a vague memory of reporting this behavior during beta 10.
This seems to be a minor bug to me. The open/closed state of palettes and what they display is part of the Work Environment - even the dynamically adjusted one - and is saved in the ArchiCAD preferences, not in the project file. Only if a view is defined, redefined, drawing placed, etc etc should the prompt happen.
Cheers,
Karl
