[RTTY] Problem with fldigi

[Bill Turner]

Odd thing with fldigi.  Running latest version with gateway to DXLab
suite. Rig is FlexRadio 6300.

After fldigi starts with Olivia it runs for about a half minute
normally and for no reason I can see, it sends a command to the radio
to change modes. I then manually change the mode back and all is fine
for the rest of the session. It does this every time. 

Any suggestions how to fix?

Thanks,
