Problem:

On Windows 10 - Starry Night 7 Remote SkyGuide, in part, uses the Windows Internet Explorer framework, and if javascript is not enabled for IE, then remote SkyGuide will fail.  

Test:

You can test whether this is the issue by navigating to the following web page using Internet Explorer:

If the webpage says javascript is not enabled then it must be enabled.

Solution:
