Hi Jim,
Because of the way that DayBack for FileMaker exports the event and filter to the temporary directory in order for the web viewer to display events, there isn't a good way to have the calendar showing in separate windows with different filters. The scripts really aren't written with that in mind either, so there would be some changes required for them to know which window to focus on:

You'll be able to download a preview of the new DayBack as soon as Claris offers a public preview of FileMaker 19. More details can be found here:
