Links require password when spreadsheet opened already!

I have a lot of links between two of my spreadsheets…all one way. Even though the master spreadsheet is open on the machine, the slave spreadsheet requires the password before SOME of the links will work. Some work OK. Some of the links are in the format =DDE(" etc and some are in the format ='file:// etc. I am not sure why this is the case. How can I ensure that the slave spreadsheet does not require a password if the maste spreadsheet is already open?

The problem has only arisn with 4.3 and did not happen in 4.2…I think it must be the non DDE links…

I am LO and Ubuntu 14.04.

Please verify if you have differences in Menu/Tools/Options/LibreOffice/Security.

I am sorry, I don’t understand what you mean?!
