I have a modal form and on that form is a grid. Double-clicking one of the grid columns brings up a modal drill-down form which also has a grid on it.

The problem I'm having is that if I move the drill-down form to see the contents of the original form, the image of the drill-down form stays where it was. The form does move, but an image is left behind so that I can't see the original form.

What might I be doing wrong?
