I think if that button is not assigned to anything and you press it, it's the equivalent of a right-click. The Windows 10 version of MobileSheets switches to the selection tool if you right-click, so that's why you are seeing that behavior.

I can update the code to use the first visibile layer as the active layer instead of defaulting to the first layer in the list. That does make more sense.

Thanks,
Mike
