[Dx4win] Problem with DX4WIN and MMTTY

[Donald Unruh]

When I try to use the function keys to send I get an error message of "an exception has occurred - device already open" , my 756pro keys and sends diddles. I can close the error window and hit a macro not containing "%X" and can send the macro just fine so the problem seems to be with the "%X " transmitter key command.  MMTTY ran alone in FSK works fine only when I run it from DX4WIN 7.02.15 do I have this problem. Also if I run AFSK everything seems to work OK.
 
Any ideas?
