Problem accessing MS access database from MS Word

I am using the following code in MS Word to access a MS Access database:

strDatabaseName = "C:\AccessReferences\Patient Information.mdb"
strSQL = "SELECT DISTINCT * FROM Contacts WHERE (([Contacts].[FirstName] & "" "" & [Contacts].[LastName])=""" & strName & """) OR ((Contacts.CompanyName)=""" & strName & """)"
With ActiveDocument.MailMerge.OpenDataSource strDatabaseName, wdOpenFormatText, False, True, True    ', , , , , , , , strSQL
GetFaxNumber = ActiveDocument.MailMerge.DataSource.DataFields("FaxNumber").Value

This has been working fine for years but a few months back, I intermittently get these three popups for each lookup (I click on OK or Cancel on each popup and the data is still retrieved from the database):How do I stop these popups?  Thanks.
