[Dx4win] Com Port Issue

[n4dsp]

Hello Jim,
as per your instruction leaving it on COM 7,,,
I do leave it on COM 7 but upon wakening
in the morning it's on COM 3 in Ports of the Device
Manager! So in dx4win I set File/Preferences/Radio/COM Port
to COM 3 and four hours later in Device Manager it's back
on COM 7!!
Running Windows 7 Enterprise.
Thanks for the other advice.
Merry Christmas

john
