It does remember the setting of size reduction from last time used
I assume this does NOT mean the reduction setting is checked even after I sign out.
The 'cancel' after sign in works well enough, but as you say, not very intuitive.
I wonder if you can check to see if I am already logged in to the 'normal jAlbum forum' so I don't have to log in at all. Obviously a potential problem if you share a computer, but otherwise... Just a thought.
