Hi,
I'm sorry, but i can't provide any test programm becouse our data is confidential.
It would be best if you sent me the new library for me to test. I also mention that we have allready bought the component MyDAC and wold like to see this working.
Best regards.

We have not completed investigation of this problem yet, so we cannot provide you with the fix.
You can reproduce this problem in a small test sample and alter your confidential information with a nonsense data. You sample would help us very much.
