Hi, all -

We have a very interesting little problem, which we can replicate. I was wondering if anyone else can verify that this is happening...

There is a (baseclass) combobox, named "Combo1" on a (baseclass) form. It is the only control on the form.

Combo1.When:

RETURN .F.

Combo1.Init:

LOCAL ln1, lc1, i

CREATE CURSOR cTemp1 (x C(10))
FOR i = 1 TO 20
	APPEND BLANK
	REPLACE x WITH 'Value ' + ALLTRIM(STR(RECNO()))
NEXT i
ln1 = 3

SCAN
	this.AddItem(x)
	IF RECNO() = ln1
		lc1 = x
	ENDIF
ENDSCAN
GO TOP
this.Value = lc1
this.Refresh()

Next, we run the form.

I would expect that the value of Combo1 cannot change, since the When( ) method returns false. This is not the case. The user can click on the center of Combo1, then drag out of Combo1 (either up or down). This changes the value, a little. Usually only a few values up or down.

This is very scary behavior, as we have hundreds of forms with comboboxes on them, and the default behavior of the framework we are using is to have:

RETURN thisform.editing

in the When clause of all objects, and to only allow editing at certain times.

Can anyone else replicate this (assumed) bug?

BTW, this behavior can be replicated in the following versions of VFP:
