Hotspots that are only used as
bookmarks may interfere with hyperlink hotspots
2.0 - 4.4
When a hotspot is used only as a bookmark or as the initial viewpoint
but not as a hyperlink, it should be excluded from the VR file. Otherwise
it may interferes with the operation of hyperlink hotspots that it
overlaps (if any).
Corrected in V4.5. Hotspots are now excluded from the VR file if the
Hyperlink URL and Hyperlink Bookmark fields are blank and the
Show hotspot option is set to Normal. Otherwise the
hotspot will be included in the VR file.
