Ok, I'll try a complete new built. But if it doesn't work I'll invoice you the time it takes
edit: Getting even more weird, I haven't built a new version yet, but now I see that one (=1) thumbnail of the 5 new ones I added is used in the menu. So I assume their IS a bug somewhere.
edit: Seems to be confirmed now, as this single panorama was newly built because I had changed the name. Just change the name, and the entire panorama needs to be rendered new *sigh*
Nad one only can change the thumbnail by building complete new tiles *doublesigh*
Someone seriously needs to do his homework.
Part one of the homework is done (on developper side, not in Beta4), if you rename the panorama, the tiles are not re-built.
Part two of the homework is still to be done, if a new thumbnail is set for a panorama, it is not re-built, the old thaumbnail is kept in the tour.
But this part should be easy to fix.
If you do not want to wait next release, and do not want to rebuild all the tiles to create the new thumbnails. Just open your favorite file system browser (Finder, Windows Explorer, etc..) in your tour directory, find the files named thumbnail.* in the tour, delete them. Rebuild the tour. Only the thumbnails will be regenerated.
