Mark,

It is not a bug. This is the way it has worked since Valid events where first invented.

Return .F. will always display the default Wait Window message

Return 0 will allow you to specify your own Wait Window message

PF

>When you edit the valid event, you can either return .T. to allow control to loose focus or .F. to force it to retain focus.
>
>The bug here is that when you return .F., VFP6 automatically displays an 'INVALID INPUT MESSAGE'...Is there a way to remove that message or at least change it?
>
> In the days of DOS, it used to be done by adding ERROR 'New Message' in an @Get statement...

>Any help would be appreciated...
