Thank you very much, I appreciate the kind words
The "EQ Mail" button mod can be removed simply by deleting the EQUI_SelectorWnd.xml file out of the folder. This will return the Window Selector that you are referring to.
The HP/Pet Bars/SQ Gem, is the same in all of the Integrated Series.
- Click on the Square, the Name of the player, or the Red HP bar to target the person.
- Click on the green bar to target the pet of the person, or hit the appropriate F-key 2x.
I haven't really had any issues targeting by clicking as a Beastlord or Cleric, think it may be mouse related?
Again thank you and hope my suggestions make it easier for you.
