How to un-tile your program when the onscreen keyboard is removed?

In at least Windows 8, at certain resolutions (a MS Surface Pro, for example, 1920 x 1080 with "Larger - 150%"), if a desktop program is maximized (or would otherwise intrude on the onscreen keyboard space) and the onscreen keyboard is activatedand the onscreen keyboard is maximized (or subsequently maximized), then that forces our desktop program to be tiled above the maximized onscreen keyboard. All is well, until the onscreen keyboard is restored to its non-maximized size or dismissed. We'd like our desktop program to resize itself to its original position. But we're having a difficult time finding out how to get a notification that we can resume our original size.

Any suggestions?

Thanks!
