WebPage.show optional parameter and WebPage.PopupBlocked

http://documentation.xojo.com/index.php/WebPage.Show say that it can take (InNewWindow As Boolean), but then in the notes it say:
Beginning with 2011r2, Show does not take the optional parameter InNewWindow.

There is a reference on that page to WebPage.PopupBlocked, but if we can’t put the optional parameter, then I guess PopupBlocked is no longer available. Also PopUpBlocked is not listed here: http://documentation.xojo.com/index.php/WebPage

Maybe it is a good idea to change the information on WebPage.Show and remove WebPage.PopupBlocked?
