Here's the example:
I have a windows forms application, the main (startup) form is an MDI Parent form. I want to display an image as a background picture for the application, centred on the screen. If I set the background image for the form, the image repeats and I can't see an obvious property that will prevent it.
If I add a picturebox to the form, I can get the image to display correctly, however any MDI Child forms that are opened, open up underneath the picture box.

TIA
