PGP Not Accepting Domain Password on ThinkPad

I had problems with my laptop after installing the PGP desktop (in order to use the PGP Whole Disk Encryption).  Most times, when I would reboot, the PGP boot application would not take my domain password.  I would have to use a one-time recovery token to get booted.  A co-worker found, in the PGP forums, a reference to this being a conflict with the ThinkVantage fingerprint software for some ThinkPads (T400, T500, X301, X200, W700, etc.).  I uninstalled the fingerprint software and the problem stopped immediately.  I ran this way for more than a week without any issues.  I installed the fingerprint software again and, so far, it seems to work.  Time will tell if the problem comes back and the fingerprint software has to be uninstalled again.
