Hi,

Previous in 7.5, there was a Staff plugin SPNG that allows you to
know when your contact opens a window with you or closes your
window, any idea where could we still get that for live?

thanks!

Edit: at the bottom there are some script you could use

And in case you wonder, you can find the current version of StuffPlug on http://www.stuffplug.com. Please note however, that it does not have the feature you requested because of the reasons in the post scott2010_h linked to you.
