For a temporary work-around, you can re-position your second monitor in the Resolution config in Windows. Just join them at the corner so that there is a tiny gap of overlap between the sides, so that you can still move your mouse cursor to the other window.
Also, you'll still be able to move applications between monitors by using Windows Key + Direction Key (left or right).
Here is a screenshot example for how to line up your monitors:
