EkerIPAddress is not my skin Krill... Try to contact the user who created it through a note on DeviantArt. That's why I told you that for my skins I always use the netmonitorcore.
and I'm not the Developer of XWidget
Tony is the developer of all the apps here.
Your request about the pop-up window maybe can be done but you need to involve some java script coding there and sincerely I never used this realtime pop-up info. XWidget supports pop-up tooltip but you want a more advanced function and requires some coding. But as I told you, you can add,remove or edit any part of a widget.
It's hard to explain some things to a new user. That's why I suggested you to check from the inside ready widgets, play with the settings and check topics in the above sections. I did the same when I discovered XWidget, I didn't know anything about it and now I have more than 4000+ widgets in profile
