Thanks for your answer. I think I should update to the latest version. Did not realise, it was that long ago, I updated my component pack.
I have installed TMS Component Pack v9.2.0.0 release May 28, 2019
I just saw, that the Component Pack does not exist any more. I guess the TMS VCL UI Pack replaces it.
Sorry for my requests, that most likely are caused by a very old version. I will buy updates tomorrow and try it with the latest version.
Thanks a lot for your patience.
