I have typically used Constant Contact by opening different areas of the site in separate tabs at the same time. For example, while working on a new email, I might click on the "Campaigns" link to open it in a new tab & review a past email to see how it was done. However, now when I right-click on any of the Main Menu items to open them in a new tab, the new page is totally blank with "about:blank" as the URL. So it's something of an inconvenience...
