I went to their web site but I don't see the plastic part. I understood the words you used but I still can't see where the spring attaches to the "nub" on the latch or on the frame. Do you know of a diagram or schematic?
Thanks for the explanation. I know computers can be a pain. But while your answer was helpful it really didn't solve my problem. But I want to be fair. How do you think I should proceed? I don't think I should pay for advice that didn't complete the task.
