Paradox 11 Runtime - Unexpected crash

Under certain conditions I recieve the following error when closing a database "The PfW Runtime has stopped working"  

This occurs when I open a database with the following switches (Sample shortcut command)

"C:\Program Files (x86)\Paradox Runtime\Programs\pdxrwn32.exe" -c -q -wN:\PortData_V11\CoastalAmerican N:\PortData_V11\CoastalAmerican\mainmenu.fdl

Once the application opens,   it will run as expected until I click the command X on the top right corner of the app window (not the open form, the APP).

If I choose File Exit from my menu or if I click the X in the top right of the open form,  it exits properly,  both of those options have code associated with them that shut down the database.

Does anyone know the cause of this OR does anyone have a code snippet to intercept the click on the app window?

Thanks!

you mean closing paradox itself, with your app open, causes the abort, correct?

you have cleanup code in your app, that closes everything first, but something that's open is causing the abort, externally

if you have a full copy of paradox, and if you know what your "close" event is doing, you can replicate and test, in full paradox.. it could be tcursors that aren't closed and/or the associated locks

Is there a tool or process that shows open libraries and tcursors?

not that I'm aware of

Turns out the runtime was crashing beacause of interdependence of certain libraries.  The order that they were opened and the order that they were closed cause the crash.

Open LibA

Open LibB  (which also opens LIBA because it has a dependency on LIBA)

Open LIBOthers

Close LibA

Close LibOthers

Close LibB   = Crash

Simply closing them in the reverse order that they were opened fixed the issue.
