I was only using Aero as an example. It is possible to capture, monitor, manipulate, and send messages to windows that are minimized or not shown. Windows will not stop using this because every computer from 98+ comes with DLLs capable of such things. And if they cease to provide it, they still exist. As far as the average user being able to do it... That's unnecessary. All it takes is one developer to write a basic library of functions in which other scripters can create bots with. All the average user has to do is DL the program and hit run. ^ Only a select few will know the real irony about me posting that paragraph... Lmao (Not referring to RS_Functions, if that's what you though). As for quite demanding on your CPU, the DGSweeper monitors 3 different areas of your RuneScape applet every 50MS while drawing on two different canvasses, creating 2 different map bitmaps (with and without keys), calculating the timer, calculating position/size, etc... It'll never jump past 1% CPU usage on my machine. Some method, such as standard pixel searches will hog resources, but not if done properly. ;).
