Can unstored calcs evaluate in Find mode?

[Mandu]

I have a data-entry layout that includes a button for toggling a boolean field (Number, 0 or 1). Superimposed on the button is an Unstored Calculation that evaluates to a Container with either an image of a checkmark, if the boolean is 1, or nothing otherwise.

Clicking the button XOR's the boolean with 1. In Browse mode this triggers the Unstored Calc to show or hide the checkmark. But in Find mode, while the button still works and sets the boolean, the UC apparently isn't being triggered - at any rate, no checkmark appears.

Do UC's in fact not recalculate in Find mode? Is there a way of accomplishing what I'm after? (I'm really hoping to avoid having separate layouts for Data Entry vs. Find.)

Thanks,

Chap
