Hello! I have this problem with progress bar too, and it's not сaching! After upgrading krpano.swf from 1.0.8.15 to 1.16.1, I can saw only default progress bar with wait animation on each of old panos.
The old showload="bar(center,400,50,0,140,shaded,0x000000, 0xDDDDDD,0xAAAAAA)" don't understanding, and even none/none do not hide a default bar.
I have tested a copies of all files with new names => it's not caching.
What the problem it can be?
