Mouse Wheel at Runtime

[Scott24x7]

I just noticed an odd behavior in my mouse and VFP. I have several grids on a form. When I am working in development mode (i.e. I'm running the app within VFP), the mouse wheel works as expected. (If I am over a grid, and I move the mouse wheel, the grid moves along with it, up and down). But if I run it as an .EXE the mouse wheel does nothing.
Any idea what causes this, and how to fix it? Anyone else have this same issue?

Ver: VFP 9 with all the SPs applied, Sedna applied, on Win10.

Hi,
The corresponding grid or one of its controls needs focus - just click on it

Nope, that doesn't work.
And MouseEnter is all that's needed to tell the object that a mouse event is taking place.

Most controls react to mouse wheel, if you just hover them, even whole applications like notpad don't need to be activated before reacting to wheel events, it's sufficient you hover them.

But indeed VFP grids need to have focus before they react to mouse wheel events, also at design time.

Do you prevent focus to be on any column control? If you make use of AllowCellSelection=.f. instead of RETURN .F. in When events, the grid can get (readonly) focus and you can scroll it.

I don't see a difference between running in an EXE or within IDE, in form designer grids won't scroll, as they don't show data at all.

This is another that is really bugging me, because everything you guys have said makes sense, but its still not working.
In fact, if I click the record in the gird to make sure the grid is not just in focus, but I've click on a row, and then try to move it with mouse wheel, it still does not move in the .EXE. I can only move it with the vertical scroll bar at the right (either clicking in the bar, or clicking the arrows at the end of the bar, but mouse wheel doesn't work when I'm over the bar either).
I'm beginning to think it is some kind of issue with drivers or the mouse I'm using, but that seems unlikely because it works when in the IDE...

BTW, I've resolved the need to click a grid to get the mouse wheel to work by just hovering with this code:

LPARAMETERS nButton, nShift, nXCoord, nYCoord
*
IF UPPER(ALLTRIM(WONTOP())) = UPPER(ALLTRIM(ThisForm.Name))
	This.SetFocus()
ENDIF

I've commented this out to see if this was an issue with the run time, but even when I click in the grid at runtime, mouse wheel is still not recognized. While running as an APP in the IDE, it works fine...
