like you know when you switch away from the program it goes to the multitask bin. like how do i completely kill the program.
I'm not really sure. I prefer backgrounder which works better in my opinion. I just know that before multitasking, specific apps where able to go into standby mode like state when closed (such as Safari) so they don't free their resources for faster reopening time. If there aren't enough resources, apps on standby get completely closed out to free up resources for whatever you are doing. This is easy to tell in Safari by opening up a page (multiple pages goes faster), close Safari, do a bunch of stuff to use up resources, return to Safari, and if the pages have to reload, then you know the pages were cleared to free up memory and such.
As far as Apple's multitasking goes, I don't really use it much because I find Backgrounder superior. Maybe reopening the app and closing it normally is how?
