Carl, I hesitate to suggest something quite so obvious, but it seems to me that each time you enter the On Startup method, you
1. Set $dataPath to a path 2. Test $dataPath is “”, which of course it isn’t 3. Open a data file 4. Set $dataPath to “” (effectively pointless) 5. Re-enter On startup when the new data file opens 6. Go to step 1; hence your loop From the OPEN DATA FILE documentation: If the access path sets a valid data file, 4D quits the database in progress and re-opens it with the specified data file. In single-user mode, the Semaphore <file:///4Dv17/4D/17/Semaphore.301-3730607.en.html> and the On Startup database method <file:///4Dv17/4D/17/On-Startup-database-method.301-3730029.en.html> are successively called. Warning: Since this command causes the application to quit before re-opening with the specified data file, it must be used with precaution in the On Startup database method <file:///4Dv17/4D/17/On-Startup-database-method.301-3730029.en.html> or in a method called by this database method, so as to avoid generating an infinite loop.
