After downloading the .zip file, and before extracting contents, right-mouse click the .zip file, choose "Properties", then at bottom of "General" tab (default that opens) toward right check "Unblock", then select OK. If you've already extracted everything then alternatively do the same thing on the VarAC.exe file either before or after copying it to your installation folder ... right-click -> properties -> check Unblock then OK. Windows will then not recognize the exe as a potential threat to your system. Hope that helps! 73 de KI0ER

Thanks for that suggestion! However, I'm looking for the first time at my .ini file, and it has the following by default: ShowNoCatQSYPopup=ON So, that seems to indicate that Show NO Cat QSY Popup is already True (ON). Yet I'm seeing them as I've discussed. Or should that be set to "OFF"? Which if that's what I should do, that's a double negative or something quite counter intuitive, right? I believe the modal dialogs should just be gone. It also does not solve the problem that my QSO partner gets a message to QSY to a frequency, not a particular slot, and the subsequent refusal to QSY message I receive. I'll change the "ShowNOCatQSYPopup" to OFF and see what happens when I have the opportunity. Thanks again for pointing that buried setting out!
