Links not getting updated

I am trying out Libre calc 4.11 with an existing Excel spreadsheet that relies on links to other .xls files. I have Libre set to update links automatically on starting, but it fails to update the links. Excel updates them without trouble. How do I get Libre to update the links? Even manual update does not work.

Clarification: The sheet was generated with Excel 2003 in a Windows 7 environment.

The are a number of currently open bugs for “link”+“xls”. There is possibly one in that list relating to your particular usage.
