I made a dummy project with:
- Database with one table "Table1"
- One form (based on VFP class) with "Table1" in the data environment (Exclusive = .F.). Dragged the table into the form to create a grid. No other modifications done to the form
- One main program that call the form and issue a READ EVENTS

Compile the project into a .EXE

Run the .EXE

In the status bar, I see that the table isn't open exclusive (when you open a table exclusively, you see "exclusive" in the status bar)

Run again the .EXE while the other one is still running. I get the error message at this point.
