Thank you much, George. That will settle my frustations and doubts.
All the styles that I downloaded end in .STY, nowhere do I see .STT, though. But I found some more that load and play and it is a matter of finding out.
The site where I got them may have changed all terminations to be even STY.
In which place are the files with the .STT as you describe?
Thanks again.
