G'morning shaeman and welcome to the forums!

look for v1.8i (alpha out now,.. official to be released in a bit) and update your local version. then turn on 'focus-follows-mouse'... this makes looting on your alts MUCH easier. basically, just move your mouse to the other screen and click once to loot.. like you would on your main.

without 'focus-follows-mouse' you have to click to activate the window, then click again to loot. workable, but doesn't flow very well and is inconsistent with how you play your main.

if you have any questions or comments, please feel free to drop me a note.

have a great day and welcome to the family
