You have to press return or tab after entering the figure to confirm
it before pressing OK.

What I hadn't appreciated, before experimenting as a result of this
thread, is that there are circumstances where Ovation Pro seems to get
confused. If, with Brightnesss=0 you enter a number, say 50, into its
icon then immediately click "OK", pressing the return key subsequently
will then not confirm the new setting of 50, even if you delete and
replace it before pressing return. You have to replace it with a
different number for return to register the change. But if you enter a
new number, click OK without pressing return so that the change is not
registered, then use the nudge icons (which I don't usually do) these
operate relative to the new, previously unrecognised value. Thus,
starting with brightness=0, change that to 50, click OK (brightness
appears unchanged), but then click nudge left to increase it to 51 and
the displayed brightness suddenly changes from normal (0) to very
bright (51%).

In the Process dialogue box, the return key, like tab, cycles
endlessly between the three writable icons and, as shown, acts on
changes immediately. For some other dialogue boxes with writable
icons, return moves, more conventionally, between fields until it
reaches the last where it acts as the OK button, but for these boxes
the changes are not made dynamically as the caret moves from field to
field, but only when OK is reached. For such fields (e.g. "Scale" in
the "Modify picture" box) the new figure will be used immediately on
"OK", regardless of whether or not return was pressed.

Odd -- or at least inconsistent.
