  Function definition: (Copy & paste into FileMaker's Edit Custom Function window)

Tests whether a FileMaker for Windows document window is maximized or not. Returns a one if the window is maximized, and a zero if it is not.

Note 1: this CF does not test the maximization state of the FileMaker APPLICATION window, only the document window.

Note 2: this CF always returns a zero on the Macintosh platform.

Hello Kevin, thanks for this function I've used it in a couple of solutions recently.

A question for you: are windows in FM GO in iPhone and iPad maximized? What should the function return for these?

We live in exciting times!
