Use mouse location to place autoshape via VBA

[ker_01]

I'm have a worksheet with an imported picture. I'm using the mouse X/Y
coordinates to identify specific points on the picture, which will be used in
calculating the location of autoshapes that will be placed with a later macro.

To make sure that I'm headed in the right direction, I set up my code to
move a small autoshape to the mouse location when I click on the picture. I'm
getting reliable X/Y coordinates, but the autoshape is not ending up where
the mouse is. (autoshape top/left = pox.y and pos.x)

At this point, it seems likely that the mouse X/Y is actual (anywhere on the
screen or toolbars) whereas the autoshape is maybe offset from the top left
of the worksheet(?).

I won't be the only user of this worksheet, and different users may have
different numbers of toolbars/menu/etc. What is the most reliable way to
identify the relative start point for an autoshape placement, and work
backward to my actual mouse X/Y coordinates?

Thank you,
Keith

Debug.Print Str1 & " 2. " & Pos.X & ", " & Pos.Y
Sheet2.Shapes("Oval 2").Left = (Val(Pos.X))

{userform 1 has two text boxes and a submit button; these are values to help
me insert the X/Y coordinates onto a second sheet for permanent storage)}
