A couple of possibilities here. First, your other answer to this question is correct, you must be sure that the Notes.ini and other files are all available when the PC is not LAN connected. Also, if the PC was last used with Notes is LAN mode, it may be looking for its server and getting stuck. Check to be sure your location document is set to LOCAL or whatever your no LAN location document is called.
Search your HArd Drive for Notes.ini, make sure that :-
A> It exists!
B> It is on the PATH
C> It is not Write Protected
D> It has been recentl;y modified
Notes modifies the Notes.ini every time it starts and/or every time the user changes a setting that needs to be remembered next time the client is used. If your Notes.ini on thehard disk is not date/time stamped the day & time you last used Notes, it is not the one being used. This would indicate your notes client is looking on the LAN for its Notes.ini file.....hence the problem when you are not connected!
If none of this helps, post more details on the configuration of your laptop and notes client...
