First off you'll need to add the new include to eq2ui_mainhud.xml. This should make the window available in game.
If you use a customized keyboard setup, you'll probably need to assign a key to the new window. At least for me, F11 did not automaticly get mapped to the new window. To do this, open Game Options and find the Window Keys area (I think its under User Interface?). The last option there should be for the connection window.
In some cases the new Connectionstats window may come up offscreen. To resolve this issue do the following...
1) From the EQ2 Start menu select Locator
2) Select Mail from the window selection menu.
3) Paste the following into the script box
Code:
.parent.Connectionstats.location="300,300"
4) Press the apply script button
This should move the window to the upper left corner of the screen. After you repossition the window manually, it should save in the new location.
