What happens here is my bookmarks still show on the bar, but they show as grey with no color and the URL is blank. I can restore them using Bookmarks/Manage Bookmarks/Import and Backup/Restore, but this is happening at least once a week on both my and my wifes HP Desktops. I am wondering if it may be related to Iolo System Mechanic, which we both use to keep our computers "clean"?
