I see you joined on the 9th of Dec or something like that...
Lets see if this is appropriate. Every program you open.. is NOT closed when you use the "X" in the upper right. It just minimized the app. If you look in settings and memory , currently running programs you've got a cute little mobile version of the task manager.
Dude CLOSE that stuff you've had open all day... read read read and read more on this site and decide to grab an add on that automatically closes applications when you select the X.. I personally like WKTask since it give me a task bar like a desktop OS but as learn more as we read more I initially tried the HTCX button add on but the task bar app. is much cooler --- to me...
" i only run one program at a time as much as i can, "
Check in settings memory and see if you really running JUST ONE Program ...
Rep me if I helped
peace in Christ
