How do I turn off Popup Blocking?
A Popup Blocker will prevent you from seeing those pages linked via Hotspots in the panoramas. You need to disable any (and all) Popup Blockers for this program to work. There are many different types of Popup Blocker, and many different ways to disable them, either temporarily, always, or for a specified site only. Here are just some of them...

Internet Explorer 6 (with XP SP2)
      Select Tools / Pop-up Blocker / Turn Off Pop-up Blocker.

Firefox
      Select Tools / Options / Content, and untick "Block Popup windows".

      Select Tools / Options / Web Features, and untick "Block Popup Windows".
