[jitsi-users] Jitsi not remembering password for one user


We have about 10 instances of Jitsi running on various OS's.
One, and only one user has this problem. Every time he logs into his computer, he has to reenter his xmpp password in Jitsi.
Especially if the computer is woken up from sleep or hibernation.

We've tried many things, including entering his credentials while running Jitsi as "administrator". Nothing has helped.

Jitsi 2.8.xxx
Windows 8.1 Professional

What should I look at?
