The Flash Player developers regularly visit this forum, and they do answer questions that are answerable.
I do believe you that you have a problem with Flash Player, and yes, many other users have posted similar problems.
The problem that Adobe has is that they cannot reproduce it. I cannot reproduce it. Software problems are very difficult to diagnose if they cannot be reproduced.
I remember one user who posted one or two years ago that he would always get Flash Player hung up or not responding when he has more than 2,500 Flash Player tabs open on Firefox. Well, that is certainly not something I am going to try and reproduce.
If you can tell what exact steps lead to your problem, maybe then the Adobe engineering team will be able to reproduce it.
