>>When I have programmed screens with grids on them and I click on the grid, it moves the screen and usually hides the controls that I have at the bottom of the screen. Is there a way to prevent this? Is it a bug in Foxpro?

I was about to post the same problem when I found this thread in my search. Two of my grids make the whole form jump when they are clicked. The other grids don't do that. One of these grids has code in its click event which runs another form. The grid.click is called from the .click of each grid.columnX.textbox. The jump causes the adjacent record to be selected. The other jumping grid doesn't have .click code. My grid class has these procedures:

basegrid.When

IF RECCOUNT(THIS.Recordsource) = 0
	RETURN .F.
ENDIF

It jumps only when there are records in the grid, so the .When doesn't return .F.

basegrid.BeforeRowColChange

LPARAMETERS nColIndex
IF LASTKEY() = 13 OR LASTKEY() = 9 && [Enter] & [Tab]
	IF nColIndex = THIS.ColumnCount
		KEYBOARD "{CTRL+TAB}"
	ENDIF
ENDIF
IF LASTKEY() = 15 && [Shift-Tab]
	IF nColIndex = 1
		KEYBOARD "{CTRL+SHIFT+TAB}"
	ENDIF
ENDIF

A mouse click shouldn't put a 9, 13, or 15 in LASTKEY() and a WAIT WINDOW confirms that it doesn't.

I am not using a framework and there is no code changing the value of form.top. It doesn't seem to matter if grid.ReadOnly is .T. or .F. It really looks like a grid bug, and it's maddeningly inconsistent. Someone else must have seen this. I use vfp6 sp3.
