Log4OM

Hi,I set up fl digi according to the Manuel and got the virtual port working.It works but was curious about something.I don't need to connect Fl Digi in Log4 OM.Does it have to do with the fact that I set up my radio to work directly with Fldigi as well.I can connect Fligi in Log4om and it works except when I change bands the radio doesn't switch correctly.It switches then goes back to the band I was on
