Dialer wont close on Mogul

[weezi84]

I have a problem and I hope the geniuses here at ppcgeeks could help me with. Everytime i close my dialer for some reason it still runs in the background, sometimes three phone dialers running at the same time which causes my phone to freeze up. When i run opera it crashes and so on and so on. I was wondering if anyone experienced this on their mogul as well
