Re: [Condor-users] kbbd issues

A question, which version of Condor are you using?  There was a
problem with the kbdd in earlier versions wherein after a suspend, the
kbdd would not update the address of the startd it is supposed to
communicate with, and thus all keyboard/mouse updates would get lost.
This was fixed sometime after Condor Week last year after Ian from
Cycle brought it to our attention.
