// selected before leaving the page, and not the initially selected tab.

|
|
// going from here...

// a script block located RIGHT AFTER the body tag (this seems to prevent
|
|
// an edge case bug on IE - IE seems to sometimes forget the history when
|
|
// coming back to a page, and the back - or forward button depending on the
|
|
// situation - is disabled...)
