Here's what ya need to do:
1. Run WoW at 1024x768 in WINDOW MODE. Do not change any default settings, as this macro relies on default window settings in WoW. If you aren't running the default WoW interface, this most likely WILL NOT work. Also, your window MUST BE at the very top left hand corner of the screen. You can accomplish this by changing your resolution to 800x600 in window mode, then back to 1024x768. DO NOT MOVE YOUR SCREEN AFTER THIS! I will add a function where you can move the screen around eventually, but that's for v1.5!
2. You must be running the default "blue" Windows XP theme! This is crucial due to pixel color checks. Being one pixel off can ruin your macro! The theme is called "Windows XP" in Windows. Ya can't miss it.
3. CLOSE YOUR MINI MAP! Some colors in the mini map can confuse the macro, so close it before running this!
4. TURN ON "CLICK TO MOVE" in your "Interface Options". Press ESC then click Interface Options. Then turn on "CLICK TO MOVE!" IF YOU DON'T DO THIS IT WON'T WORK AT ALL!
7. I haven't put any sort of looping mechanism so put the "number of times to run" at an acceptable number in ACTool.
8. Find an area with non aggro mobs to use this macro in......it will not attack aggro mobs you jump you. Trying to figure out a way to handle this, but there is no foolproof method. If that works, it would just be an auto attack/loot/skin bot. Not there just yet!

Have fun. Tested this quite a bit works very well. However servers are kinda empty at 8 AM so not too many dead mobs lying around. I killed a ton and used it, worked very well!

After you've got this portion setup, open up ACTool and paste in the macro below.

FYI, Auto Mining is next! Coming up tomorrow. :)
