Hi, yes assumptions are dangerous.
No I did read documentation, I simply seen that commenting that line no wrong behaviours happen in application execution also quitting it with alive connections.
No, I did check in depth because my focus is at the moment at other thinks, I seen only no memory leaks reported from Visual Studio.

At the moment I am testing and working without the above qDeleteAll() and it are working fine, though I keep in mind that line and keep ready to restore it if some problem or suspect happens.


Sorry for my English.

Cheers,
Giorgio
