I disagree. A dialog box in this situation has two bad effects: 1) It forces the users attention away from where the error occurs (ie in the entry box) and in an extreme case could even hide the error by popping up on top of the box beintg edited! 2) It is not specific enough - the dialog could be from another application in the background or about some other error - a network lost for example. You have to read it to interpret it. Whereas if the entry box you are typing into beeps and goes red, say, it is obvious where the error is and it's very easy to fix. As to forcing the user to correct the error a doalog is no better than a coloured entry widget since the user can just OK it and carry on filling I the other fields. In that situation you have to do a submit time check on the fields too or else refuse to allow access to any other field while the error persists. Designing a good UI is frought with difficulty.
