Default "Running Program?"

Hello!Excuse me if this question's already been asked, but I just couldn't find it. I've just done a hard reset on my XDA IIi, & installed the applications.
Why does this icon(dunno what it's really called),like the one that comes out when there's a running program(like an analog clock) just keeps popping out all the time, even if there's no program running?How do I stop it? Soft resets don't seem to work. Please advise.
