Craig,
short time before I answered a similar question in a French newsgroup by
copying (and translating) a former post of mine.
Here a copy of the English text:

Paul,
I know the same problem and its really bothering, if you change a record
without intention.
The same thing happens to me when scrolling in internet-forms with the
mouse
wheel.
I do understand your concerns.
Nevertheless I would agree with Jim. Disabling the wheel function may
appear
as a weakness of your app for the costumer.
So it's better to distinguish, which field is active and to chose the best
action (setting the event you like and disable the default or use
setErrorCode(userError).
This does not apply to actions fired by key-pressing. But to all
menu-actions, this means also clicks on icons in the toolbar, are
involved.
Please note: The wheel-move triggers first an menuAction event. Here you
can
use some method to decide what to do.
For example: I do redirect the NextRecord to FieldForward in some critical
cases.
method menuAction(var eventInfo MenuEvent)
var
siID smallInt
uiActive uiObject
stAName string
endVar
if eventInfo.isPreFilter() then
;// This code executes for each object on the form
siID=eventInfo.ID()
if (siID=MenuRecordNext OR siID=MenuRecordPrevious) then
stAName=active'name
view("Wheel or not wheel, that is the question!",stAName)
switch
case stAName="myField": ;do something
case stAName="yourField": ;do something different
;...
endSwitch
; Code here
endIf
else
;// This code executes only for the form
endIf
endMethod
>>>
