[CQ-Contest] Writelog function keys ?

[robert]

Hi All

         Well I changed computers from Windows 7 to Windows 10.  I tried 
a few things but can not get

         function keys to send cw?  Writelog will change frequency and 
all but Function keys do nothing.

         I bet it's something simple but I am not getting it.

                     Thanks for any suggestions.    BoB WA1FCN
