Thanks, Ron, I did put in the following code instead of becomeFirstResponder:
FakturaAppDelegate *appDelegate = (FakturaAppDelegate *)[[NSApplication sharedApplication] delegate];
[appDelegate.window makeFirstResponder:self.invoiceCredit];
Now nothing works...

Further do I have another text field, it should contain integers only, so I have a crude verification for it. When the content is not a int, I get a beep, just like it should, but it does not select the text field.
