Phill,
It's probably a good idea to use this type of approach to turn the page
as a separate event
getSite().getShell().getDisplay().asyncExec
(new Runnable()
{
public void run()
{
setActivePage(0);
}
});

Phill,
I'm not really sure of the whole picture in your code, but some
variation of this approach (delayed reaction to selection or delayed
delivery of selection) is likely needed.
