Title: Fixed #2210 by adding a workaround for failure of event.isPopupTrigger()

To avoid reigniting #2103, this is only activated on Windows. This basically just sees manually if the button was number 3.
I have tested a case the user has set "Switch primary and secondary buttons" in Control Panel > Mouse: works OK.
