You're talking here about at least two potential areas of difficulty in your application.

1) the handling of transactions, including use of inappropriate transaction settings
2) the handling of exceptions

>sometimes it freezes when opening the Database...

You would have to give a lot more information about what you have set up there, like which model of Firebird (Classic/Superserver), which version of Firebird...and describing the language environment, including its data access interface, would probably help to shed some light.
