When using an App Maker 1.0.4 generated iOS7 icon to open a FMGO database I sometimes get the error:
Error: <dbname>.fmp12 is currently in use and could not be opened. If the file is shared, you can open the file on the network. (If you've opened the file before, check the Recent Files list.)
If I tap OK at the bottom of the error message popup, I get through to my application on the correct layout, but the startup script hasn't left the cursor in my search field.
The first thing my startup script does is turn on error capture, but this message apparently happenes before the startup script runs.
