Thanks "mesquitebean"! The problem was exactly what you described with the non-functioning payment window (continue button not working). In fact, I already solved it exactly as you described since I noticed that the mouse pointer changes to "active" slightly above the continue button and not on it. So, I changed the scaling to 100% and it worked like a charm.
TurboTax, a lot of people invest a lot of money in your software and services for you not to care enough to fix it and have it as a main FAQ item. I have read messages from last year even that complained about similar issue and I spent close to 3 hours searching for a solution until I accidentally noticed the issue and tried the hack to fix it. Do a better job fixing/communicating problems or I'll (and hopefully many others) get my/our software elsewhere.
