Boca Bob,
I have reported your experience to the development team and I have given the URL to this thread.
Jazzmammal's advice is good, too. It's worth experimenting with the Windows display. It might be that changing the setting 'kicks' something into behaving.
Regards,
Noel
I might change the display resolution just to see what happens. But, I will most likely put it back to the Windows recommended settings. Everything on my computer displays perfectly, so I'm really not going to end up changing everything to satisfy one renegade program. I believe if BBW worked perfectly all these years, up to and including 2017 build 463, then it must be a program glitch. Just makes sense. If I get time, I'll give a few minutes to experiment. But after all these years, I know if I start, I'll look up at the clock and my whole afternoon will be shot. 463 works fine for me.
Also, I have the two-monitor thing going too. The smaller, secondary monitor fills fine. It's the bigger one that doesn't. And I want BBW to run on the bigger screen...
