My iPaq HP 4155 is 2 years old. I replaced the stylus two months ago
with a new (OEM) one, since it was worn and was fitting loose in the slot.
Yesterday, I put a new stylus in, and it fit snug. Now, it's loose in
the slot already and wanting to slide out. I think the problem is not
with the stylus, but rather that the slot itself is worn.

Is there any fix for this?

Thanks!
Scott
