you can open your desktop resolution settings that lets you drag and reposition monitors and move the one on the right down just a little to offset it. now when you move to the top right of your main monitor it will have a handful of pixels that stop you from going further right. you'll have to move the cursor down a little bit to go to the second screen.
Yeah, that might have to do for the time being. I'm just really curious as to what I had prior to moving my PC. It was so terribly convenient. If I slowly moved my mouse up against the edge of screen A, it would just stop. I had to get a bit of a running start to make it over to the other screen.
Thank you for the suggestion.
