I am working on a large TW 4 project. When I publish, all the wonderful features work but only for a few scene changes. The floorplan freezes and the hotspots disappear. Surprisingly, the features seem to continue to work in full screen mode for a while longer. The image viewer seems fairly stable even when the map feature has completely frozen up.
See link below.
Hopefully this problem will be resolved so that I don't have to rebuild this project in TW 3.
Keep up the good work Easypano.
