[Dx4win] PSK31 Menu Problem

[Joe Giacobello]

I have a very mysterious problem when I try to adjust the TX (transmit 
parameters) settings in the PSK31 window.  First of all, the tabs across 
the top of the Settings window is blank; there are no names on the tabs. 
However,  except for the TX tab, they all do respond properly with the 
expected options.when they are selected.  In the case of the TX tab, 
some options seem to be absent.  The "TX frequency, "" Net" and "CW 
control" options are visible, but there is no "TX keying" option as 
described in the manual.  As a consequence, I'm unable to select a COM 
port for my interface.  I've reread the manual and the Help files 
several times without success.  Does anyone have any insight here?

Thanks and 73 de Joe
