Hi Gang!

I have a grid that is doing some intermittent changing of a value that should not be changing.

I have a table open (a Doctor table), that has a field called doc340B (Logical).

This field is the control source for a checkbox control that is a column of a grid.

This checkbox column readonly property is set to be .T..

I have code in the the grid keypress method as follows...

LPARAMETERS nKeyCode, nShiftAltCtrl

DO CASE
CASE nKeyCode = 4
	IF This.Parent.cboOrder.ListIndex = This.Parent.cboOrder.ListCount
		This.Parent.cboOrder.ListIndex = 1
	ELSE
		This.Parent.cboOrder.ListIndex = This.Parent.cboOrder.ListIndex + 1
	ENDIF
	This.Parent.cboOrder.InteractiveChange
	This.AllowCellSelection = .T.
	NODEFAULT
CASE nKeyCode = 19
	IF This.Parent.cboOrder.ListIndex = 1
		This.Parent.cboOrder.ListIndex = This.Parent.cboOrder.ListCount
	ELSE
		This.Parent.cboOrder.ListIndex = This.Parent.cboOrder.ListIndex - 1
	ENDIF
	This.Parent.cboOrder.InteractiveChange
	This.AllowCellSelection = .T.
	NODEFAULT
CASE nKeyCode = 13
	This.AllowCellSelection = .T.
	Thisform.m_Next()
OTHERWISE
	IF Thisform.m_DataKeyPress(nKeyCode,.F.)
		Thisform.pgfScreen.RapidPage.txtSearch.value = Thisform.p_Buffer
		Thisform.m_seek(UPPER(Thisform.p_Buffer),"doctor","",0)
		This.refresh
	ENDIF
ENDCASE

When I press on the grid, I go to the next screen - good.

If I go back to THIS screen with the grid, and press on the grid again, I go to the next screen again - good again.

I can repeat this over and over - press , go to the next screen, then go back to the grid to repeat this over and over.....

BUT!!.............

Once in while (about every 5 attempts), when I press on the grid, I get a wait window that says "The control is read-only".

Why????????

And, now the control has changed the value of the field!!! If I go back to the grid, the value has changed. I then have to edit the record of the grid to set the value back.

Any idea why this happens randomly???

Thanks!!!
