'Hi, sorry this is first time to use this type service. My company has spark 2.5.8 installed. Three weeks ago my Spark Account
“stopped” displaying me & all other users as being online --only at my workstation. I can go to other workstations and login, then
myself and other users correctly appear online. My spark account appears to login properly on any networked workstation, the issue
happens only at my workstation. Any suggestions on what I should check? --( running windows XP )
