I separated your message because it's a bug in all versions of the viewer. Usually I never modified the messages, sorry for this.
I did some improvements in image loading in 0,7,1,2 and this was a bug in this part. The improvements are related with some pauses that happened when the plugin load the images, this was more appreciable in cubic panoramas. All the other hardware accelerated viewers show the images when are completely loaded, but DevalVR shows the images while loading, this requires to do some functions while loading, for this reason the plugin did pauses. Now it works better, without pauses, and more stable.
Unfortunately there was a bug with timelapse panos, but I fixed it in 0,7,1,3 version. Thanks for the notice!
To avoid these problems in the future releases I'm working in this page to test every version of the plugin (not a public page, only for my tests) http://www.devalvr.com/paginas/testplugin/index.html
. Now I will add all the features to test automatically that all works correctly before to release every version. By now I added only 8 test but I will finish this page in few days
