Phone program won't close...

[ishouldbepsychic]

So, I'm having the same problem as many of you where the available memory slowly diminishes the longer the device is on. I installed a program (not completely sure which it was) that had a task manager and when ever I look at it, I always see that there are 3-5 copies of the Phone program running. I was wondering if anyone knows how to completely close the program and if that was causing the memory to slowly disappear?

When my phone is reset I have 18-19 mb of free ram and after a while it slowly goes down to the 12-14 range.
