Ignore Prometheus2011, he has no secret inter knowledge of whats going on inside of LOs office. Im quite confident that the issue that lead to stack splitting being disabled is of high priority to them. The ramifications of the issue is extremely damaging to the future economy/health of FE. We are just going to have to cut them some slack as they are fighting a uphill battle. Not only are they having to back step thru undocumented code... it is a fact that FE was not coded very well from day one (if it was then these kinds of issues wouldn't of gone on for years.) Personally I don't see this being fixed anytime soon.
To be fair they did adjust the weight parameters as a band aid. While it is annoying, the merchant sell/buyback work around takes less than a minute. It bites but we can live with it for awhile.
