RingCentral Phone NOW requires mouse click to initiate call

I have a US account. Related case number is 08805264. I have had two chats and two phone conversations with RingCentral folks trying to resolve this. I have tried multiple versions of the app including 10.3.1 and 11.0.2, and perhaps others. Previously when using RingCentral phone on my PC running Windows 10, I could initiate a call by typing the phone number and then pressing enter twice. I did not need to move my hand to the mouse. Now, I cannot initiate the call without having to jump to the mouse and click. Functionality has been lost with the "upgrades". And even though I went back and downloaded an old version, I must still initiate with a mouse click. It seems like a small thing, but when you are making many phone calls each day, it is really troublesome. How can I get back that functionality?
