[Dx4win] Problem since upgrade to W10/W11

[David Gould]

Hi Guy,

Thanks for the explanation and suggestions.  I have re-booted the 
computer, started Win4Yaesu and then tried to start DX4Win.   No change 
in the response.  I still get the error boxes which I have to close and 
then DX4Win starts as normal.

By playing around I have found a solution.  My virtual COM port pair was 
20/21. The set-up video said it didn't matter which of the pair was used 
for the application.  I had it set for COM20, for a trial I changed it 
to COM21 and that has got rid of the problem.

That is one more niggle removed.  Thanks.

73,

Dave G3UEG

The problem started with a new W10 computer which very quickly updated itself to W11 without any input from me, so I am not absolutely sure whether the problem existed in W10 as well as it being a problem now with W11.  It is a minor nuisance rather than a serious problem.

If I just close the second box DX4Win then starts normally.
