multiple instances of Access

[Gates Is Antichrist]

Something odd just changed today in Access. It used to begin a new instance whenever I externally opened a database (i.e., from Windows Explorer et al).

Suddenly he keeps trying to use the same one. If I have one MDB open, and bang the other in Explorer, the bang is just ignored, effectively.

Maybe this is a temporary situation or specific to these 2 files (who are inbred/clone relatives). But has anyone seen this or have the explanation? Did I bang some option inadvertently?

And BTW AFAIK no macro code is in progress, which at least in Excel can lead to precisely this type of confusion.

This more-or-less self-resolved. It only appears to involve a particular pair of MDBs. Though I still wish I knew why, I can work around the incovenience.
