I think I see the issue. In the blog post, it lists the above feature as part of the "update", but if you down load the Extreme "Upgrade" manual, it seems these features are only in this version. A bit confusing, and the blog post should be clarified.
Ok, thanks. I did not realize there was another window that pops up when you click the icon. I was trying to change it in the normal display.
Just a suggestion (I know that no one likes to do documentation!), perhaps an EXAMPLE in the help system for each function. Like "here is how we change the delay for a single channel", so that each screen in the software appears at least once in the help file.
