what list? the settings\system\memory\running programs ?
if you have the htc task manager you can change it so that tapping x closes the app.
also, if you do have htc task manager, tap and hold the x for 3 seconds and it closes. rather than minimizing. that is default.
phone application is located here: my device\windows\cprog.exe
lastly, the htc task manager is great because it can close all running programs or one at a time. get it you will not regret it.
