Can't save client preferences

Hello,

i post a response (“Can’t save preferences on Mac Snow” from Christian Tillm on 28.Oct.09) to same issue on a mac. I think it is better to create a new post because i have the same problem but on windows xp.

Installed Version is:

IBM Lotus Notes, Domino Designer and Admin 8.5.1 for Windows XP and Vista English (CZ5S0EN)

Every time i restart the client following preferences are automatically changed to:

Scan for unread → activated

Encrypt messages that i send → activated

Sign messages that i send → activated

Check for new Mail every … → deactivated

Use large icon in open list → activated

Save copy of messages that i send → ask me

There is no desktop policy on server.

Why the preferences are automatically changed?

Thanks in advance
