To recreate the popup group..
First, you have to create the group that you want to pop up, we'll call it Group P. Create the group you want to show as a pop-up box (with whatever statistics you prefer) and set “Popup Use Only” under the “Show” box.
Second, select a different group, the one you have set to show on table (e.g. "Player Stats"). Still on the Group tab, select Group P under the “Popup” box. Then back on the table when you click on Group Q, Group P will be shown as a popup box
Please check my post a day before this post. I posted these exact instructs to show you that this WAS what I did before and after deleting my default popup group. The instructs are clear and easy to follow. I followed them about 10 times and set up group P and Q fine. They just don't POPUP when clicked.
Set up 2 groups, clik on display, no popup, deleted groups, retry, wash rinse repeat.
