Hello,
thank you for your input.
At least 3 or 4 forms should be active at the same time. One form shows the data in a graphic way, one shows/edits the data in a form of a list and at least form one uses the data collected in form 1 and 2.
Since the monitor isn't big enough, one or the other form will go under others and so go invisible. The button should brings this invisible form back to the forground.
Hans
