The .lck file is only there when you open a file in VW. It's to tell other users on a network who has it open and that it can't be opened by them. It's deleted when you close the file, but on a crash it remains, you can delete it.
Those are document specific settings, a new document will always have the default settings. Make any changes you want to a new document and save it as stationary to the Templates folder. Then when you use the New document menu command you can choose that file and your settings will be retained.
I just did a search of the forum on "Arroway" and found this thread.
