We've found that a few internet browsers are not pulling up the scroll bar on the add winners table.
You can do one of two things to solve this.
1. Try a different internet browser, we prefer Google Chrome or Mozilla Firefox, then you may be able to scroll down the list.
2. Under the ADD WINNER button on that page, is a link that says "click here" which takes you to our complex (classic) allocation page. From there you'll see a complete list of all winners regardless of browser.
