You should send it to my private email.
I am only interested in working with a simple sample that you have confirmed
demonstrates the problem. This is one important way I save time and gain
clarity on what the problem is both.

In the past I had a hard time with C++ Builder but you are welcome to send
me a sample done in builder.
