7027	Windows user preferences are lost when running 4550 after 4553	Don-vip	team	"Damn, I just had the following error message after upgrading to 4550:

[[Image(screenshot.png)]]

I don't know what the error was, because no backup file has been created, despite the popup saying me it would.

The only two preferences files located in my %APPDATA%/JOSM are ""preferences"" and ""preferences_backup"", almost equal each other (only one line ""gui.geometry=1920x1034+0+0"" present in preferences and not in preferences_backup).

The file ""preferences.bak"" I was expecting to find is not there. I don't know if it has been deleted or never created.

Any idea on this ? This could be a major problem if the new tested version drops all user preferences. Maybe it is just located somewhere else ?"	defect	closed	critical		Core	tested	fixed	preferences
