I have a FileMaker file (FileA) with another FileMaker file (FileB) set up as an external data source to FileA.
When I open FileA, I see that FileB has already been opened by calling the function "DatabaseNames". I don't want FileB open yet. And I can't tell what is triggering the open.
1. my initial landing layout has no fields referenced from FileB.
2. I have no scripts explicitly opening FileB.
3. I have no layout triggers at all
4. I know that simply opening FileA should not open FileB. I have set up a pair of test files and proven this.
What other things would open the ESD file? I've no clue where else to look.
