This seems to happen in a few cases, but not always and not sure whether there is any regularity to it.

A mailmerge is run on Word 2007 or later (judging by Outlook icon on the taskbar - I only got a screenshot to go by), pulling from a .csv file like it always did. However, instead of going on with the mailmerge, it pops up a dialog

"For this mailmerge you are not using an OLE DB data connection. This can lead to problems in some cases (e.g. not all records can be processed).

We recommend using OLE DB data source (see user manual or online FAQ).

Do you want to proceed?"

and the Yes/No buttons. The instance of Word is driven by automation. However, it is seen as "not responding" and the users try to close it.

Is there a way to avoid this dialog? oWord.displayalerts is not set to .f., but then I remember that it didn't really help much in some cases, when dialogs new to the current version would still pop up.
