Adam,
this problem has been reported by me and phat_bastard one month ago, to me you have not responded in both messages, to phat_bastard you said that the problem is confirmed and that you will solve soon... twenty days ago...
Well, almost one month is not "soon"...
Today I after several crashes I found out that the operator clients "freezes" Vista SP1 from time to time without any apparently reason, so I cannot run it anymore.
Let me understand, are you going to fix the bugs in the operator client now, or should uninstall the software and use something else?
