I have two computers running the same version of the Flex Viewer 2.1 and both using IIS 5.1.
One of the computers lists all the scales available using the default data sources provided, the other does not display the scales: 2, 256 and 1,128 (see attached).
I have tried re-downloading the template and placing it into the same directory. I've also attempted to replace the config with some of the other configs provided in the package.
The result is still the same.
Are there any suggestions?
