OK, good explanation..... I think you explained the problem.
I bet you got a bad seal at the diverter handle and it's running back
thru the trim around the handle. I have seen that once. Assuming
there is a shower head, there could also be a leak in the shower
supply pipe and the spout is causing enough back pressure to cause
either the shower supply pipe or the diverter to leak. I'd suspect
the diverter first. You might just replace the parts in the diverter.
(I assume you have a separate handle type). There is most likely a
washer of some type and an O-ring or packing around the stem. That
O-ring or packing is likely bad. It's worth the couple bucks to
replace those parts and see if that does it. Those parts tend to
degrade faster than the faucet ones from being dry most of the time.
