Vista and OmniPass Software

Have a small problem, hoping someone can help me solve it.. Did a Windows
Update in August and downloaded Update for Windows Vista - KB938979.
Currently using windows Vista Home Premium and OmniPass on a Fujitsu A6020.
Had a problem with Vista displaying a duplicate user after the update. Was
advised by Fujitsu to remove and reinstall the software. Did it, problem
fixed. No more duplicate users. Now, New Problem. Before the Windows
Update/Omnipass/Remove and Reinstall issues, The "Please swipe your finger"
box would appear each and every time I would start up the PC, or Lock the
PC, or put it in standby mode. Now, the screen just displays my user
account and does not display the omnipass box. The error is: "Windows
Logon User Interface Host has stopped working". The welcome screen will
look normal, then the mouse pointer will change to busy (before the problem
started, this is when the Omnipass box would appear), but now the entire
screen goes blank and then returns to the welcome screen. This procedure
would continue forever if I didn't click on the user account and quickly
enter my password, because if I take too long, the cycle repeats. Any ideas
or suggestions would be most helpful.

Thanks,

Cyg.
