Xref or Linked Maps

[#1]

Has anyone experienced this behavior when working with XRef's? When I insert an Xref or open a map that has Xref content the initial Cross Reference menu displays, when I click External Xref button FrameMaker begins to cycle with no response, then I get an Authentication prompt, when I click Cancel it continues to cycle for some time until it finally shows the DITA External Xref screen. This behavior only happens when I initially open the application, after its been opened and cycles once I can insert Xref as usual.
