On my ipad ver 4.3.1 I can't seem to understand the process of closing programs or apps. In reading the manual it says to double click the home button and it shows recently used apps. In another area of the manual it says to double click the home button & to see the open programs or apps. Further it says to close them you hold until they wiggle & press the dash in the circle. If I don't view this bar often there is a large buildup and is this using excess memory? Also even if I completely shut down the ipad the icons stay there. I guess this is hard to understand for a pc guy like me. I have always been under the impression that too many open programs slows the computer performance. Please some body set me straight as I have read the manual over & over and it seems silent on this. I know it used to be to close a app or program you press the home button once but I guess that has all changed. jim_joh
