User is Prompted for Windows Credentials at Data Load Editor When Authenticated with a Ticket via API / Data Load Editor Doesn't Use Virtual Proxy / No 'Access-Control-Allow-Origin' header is present on the requested resource

Some requests from the Data Load editor do not go through the configured virtual proxy. This causes issues for Data Market and for those that configure ticket authentication with an external authentication module in Internet Explorer.

Not all requests from the Data Load Editor are made through the virtual proxy used by the logged-on user.

Fix:
Upgrade to the June 2018 release.
