[Dx4win] DX4WIN 7.03 and digital modes

[Endorf Family]

Hello,
I am working through setup of a DX4WIN 7.03 upgrade. In PSK31 window,
messages 1 through 6 will xmit (output to radio), and messages 7 and 8 will
not. Also Control key message 1 works OK , and messages 2 through 8 do not.
All of the messages show in the transmit buffer screen, just nothing comes
out of the radio for those particular keys.

The same occurs in the MMTTY window. The same keys work, and same keys do
not work.

Any help is appreciated.
