SQL Navigator 5.5.4 - error "Control 'dpDebugger' has no parent window"

I’m working with SQL Navigator 5.5.4. Since few weeks the debugger throws the error “Control ‘dpDebugger’ has no parent window” when I try to execute a procedure in debug mode. What may be the reason?


I think there might some some corruption with the dockable layout in the stored registry.

I would like to suggest that make sure close the application, then you rename the registry key below then start up SQL Navigator to try debugger again.

HKEY_CURRENT_USER\Software\Quest Software\SQL Navigator 5.5.4\Docking Windows

Please let us if the problem still exists. If that would work for you, you can delete the (renamed) registry key.


Thanks, that works.
