Much thanks, Paul!
I've added your code change to my CMPS onlineusers module and will see how it goes. Hard to believe I'm the first to encounter this. I assume a lot of people are using vBAdvanced CMPS and your plugin. If this change stops the CMPS onlineusers module from stepping on the "most" plugin's toes, I'll call it to their attention over at vbadvanced.com. Thanks again!
