I have a form with 1 tab control, containing 4 pages. When the form is opened, the focus is set for the first field on page 1. If I click on any of the other pages, then go back, and click on page 1, I cannot get the focus set to the first field on page 1. It always goes to the second field, and since the first field has not data, I receive an error. Within the properties of page 1, on the on click event, I've tried setting the focus, but it's not working. Any suggestions?
