I have been using Word for many years to mail merge some Word docs
using a table in Access 97.

Neither the docs nor the Access database have changed in years.

Started as Office 97 and currently using Word 2003.

Since the last use a month or two ago, when I now open the Word doc I get a pop-up "Opening this document will run the following SQL command .... Do you want to continue?"

I click Yes

Next pop-up: "... Word cannot find its data source ...."

I then try and navigate to the source and get a "not authorised" error which I know is not true and the loop repeats.

I tried this on two machines - both same results. One is running XP and the other W7-64 bit.

I then went to an old PC running W2000 and Word 2000 and it all worked fine as normal.

Any idea what has happened? Looks to me like maybe a security update has broken something. Thanks.
