Why do the HACOLP pages or data windows which pop up, sometimes disappear?
The HACOLP uses pop-up windows to display data related to the interactive mapping page. These initially appear on top, but if you click on the mapping window the pop-up windows move “behind” the mapping page. They are still open, and you can bring them back to the front by returning focus to them by clicking on the page again – where you can do this depends on your computer and operating system. One option on some browsers is to open pop-ups in new “Tabs”, so that they are always easily available.
