windower4->plugins->settings.xml
Be sure you are editing the right file and in the right location.
These are the settings I use for the coordinates. On 1920X1080 it puts it more toward the right but not all the way. This gives room for all menus to open without covering any of them. but you can tweak them to your liking. Increasing the X will make it go further right, Y will make it go further down.
Code
<recastX>800</recastX>
<recastY>100</recastY>
<buffsX>1000</buffsX>
<buffsY>100</buffsY>
