Leaking Delta Shower/Tub Spout

[Nin28]

The spout on my tub spout continues to drip even after replacing the Delta valve cartridge. Any ideas what could be wrong that would result in the dripping?

Once a shower has been used, it will take 35 minutes for the spout to quit draining the line up to the shower head.
Is this what you're talking about? Or does it continue to drip all day?

Hmmmmm... not sure now. Previous to the replacement, it would drip all day. I will observe now with that in mind. Thanks!
