Thank you very much for the information.
You are right. I have tested with two pcs.
When i e.g. send "CQ HB9HQX JN36" the other pc shows only "CQ JN36". Version 5.4 has definitively a bug. I try to fix it as soon as possible.
And i remove the setup program from the download page and replace it with a previous version.
Many thanks, 73 Beat HB9HQX
