Pop-up alerts

When an update is found, an pop-up alert can appear on the screen:

Click the pop-up to open the updated web page, right-click to close the pop-up without opening the web page.

If there appears to be many pop-up notifications, holding down the shift key while clicking will open all the queued pop-ups at once, while holding down shift when right-clicking will close all the pop-ups in the queue.

If the pop-up window is not appearing, check the Update preferences.
