What's the consensus for how many responses / comments on a given answer you should continue to reply to? After 5 or so the site says 'take it to chat' but this usually isn't viable if the parties are replying hours apart.
Case in point: I posted an answer to something that is (seemingly) easy. The OP tried something and came back with 'doesnt work'. So I suggest a modification with a suggestion on how to chase this. This continues for 2-3 more rounds and it's apparent that the OP just wants a solution and won't take ownership (despite being given numerous suggestions of things to try).
I hate to give up but this seems like wasted effort. My feeling is to delete my answer - Im betting that if I don't keep on this I will get down-voted.
