As reference, I'm using a 1920x1080 resolution screen, and a 4000x2000 "bot"-view.
But, right after opening the .exe I reduce the size of the window to 1/4th, then I log in and start the bot. But even then it sometimes fails. Eitherway, for those that have VS2012 and know how to build it, just play around with the coords and the code in one of my earlier posts see what you can get done. I'm incredibly low on time so I don't know if I can even fix it to work on every resolution/screensize as IvanJo did.
