Unable to collaborate with V11 users and V12 users

Hi

My problem is that we will be collaborating with V11 and V12 users and I have found that if a Word doc has both V11 and V12 refs from different databases inserted into it the bibliography won’t generate.  Depending which version of CWYW you use (I have both toolbars) the system cannot find the other database.  This happens even if both V11 and V12 databases are open.

This wasn’t a problem when collaborating with V9 and V11 users as the V11 CWYW toolbar was able to interact with the V9 database.

Has anybody else had this problem and if so did you find a solution?

Thanks
