Mike,
It's doubtful that you are doing anything wrong, it's most likely a printer driver error or a video driver problem. You might try getting updated drivers or stepping back through them till you find one that works. What printer are you using?
>I have a simple application that has a parent (person) and child (notes) table. I have built a created a parent-child form using the form wizard. When I run a report preview of the same details that appear on the screen (one person and all their notes records), I get an illegal operation when I return to the form and skip to a record that has child records.
