I have problem with Flapper sticking in UP position. This started all of sudden without any adjustments being made to toilet tank (American Standard). I checked and both little tabs/prongs are in correct position. I have taken all the slack out of chain to handle and nothing seems to make any difference. Flapper is sticking in UP position when flushed and I can barely touch the handle and Flapper drops down and tank fills normally, otherwise water just continues to run.
