I think I'll need to add some code to the control center to automatically retrieve off screen windows for you. Paste this into the text box in the ControlCenter and hit Execute. Will pop the window into your upper left corner.
show_window MainHUD.ConnectionStats
parent.parent.ConnectionStats.Location=0,0
set_focus MainHUD.ConnectionStats
If you still see nothing it may be transparent, so just right click there, the window will be on top. If that doesn't work I'll refer you to my trusted friend the red line.
