Top List Windows have a 30-second refresh cycle, so they update much slower than our real-time Alert Windows. Alerts always come in at the top, which makes them easy to see, whereas changes in a Top List Window can happen in any column. To ease analysis, Top List Windows have a Freeze Function. To enable it, right-click into the window, and check Freeze. Once Freeze is enabled, the filter column headers turn blue. When frozen, the Top List Window does not refresh, so the data does not change. As soon as you unfreeze it, it will update and present the latest data immediately.
