how do i make the loot box automatically disappear after all the loot has been picked up or i walk away from the pile like it used to. this is very annoying for me. TIA
You can disable area loot in the Settings > Gameplay > Loot settings.
It should close automatically if you move about 10 spaces away, or you can hit the ESC key to close it.
Personally I use the Area Loot from the Loot section of RuneMetrics, and have it placed where I want it in my interfaces where it is handy for me, yet out of the way.
