LSN Password Safe and a program-switcher.
Simultaneous use of LSN Password Safe and a program-switcher (it automatically switch the keyboard layout), can lead to software conflict.
To prevent this, you can:
1. Add LSN Password Safe in the switcher exclusion list, or
2. Turn off automatic switch in switcher for the data entry time, or
3. Turn off antikeylogger in LSN Password Safe (not recommended).
In the latter case, is safer to use a virtual keyboard for data entry.
