Max, thanks for that reminder. After a couple hours with Doug on the phone and temviewer, no joy. Still no spots showing in any of the cluster windows (except for the Cluster Manager where it shows the login info). After I hung with Doug (thanks again Doug for all your time) I was away from the computer for a few hours doing other things. When I came back there was spots populating the cluster windows (F8 tab and the external cluster window). What happened when I was away from the computer I have no idea. Feeling frisky I closed and opened Log4 a few times and all cluster functionality continued to work. Software healing itself....
I'll be running Log4 V2 as much as can over the next week to see if this issue surfaces again.
