door jamming

["Willie Mack" <wmack@xxxx>]

I think my door is getting stuck on the front striker pin. I've adjusted
everything so that the door will close smoothly, but when i try to open it,
the front gets stuck. To get it open, i place a small crow bar under the
door and apply a little pressure, and the door opens up.

What is getting my door stuck?

Thanks
Willie
