All most anything you do via VBA code (from a code module, object
module, or userform) clears out the Undo buffer. You could try to
write your own Undo method, but that can get rather tricky rather
quickly.

Hi, I have a dialogbox (Set shp1 =
ActiveWorkbook.ActiveSheet.Shapes.AddShape(msoSha peRectangularCallout, lft +
wth - 9, tp - 5.9 * hgt, 110, 65))

that is called in a selectionchange event, the problem is that when it is
called the undo is lost, I dont want to lose the undo, therefore I thought
about using a Userform (modeless), the problem with the userform is the form
(I wanted to be like msoShapeRectangularCallout) and the background color (I
want yellow with 40% transparency and no border lines)

the rest of the thinks I know how to accomplish (possition, etc).

any suggestion will be appresiated.
