Hi Frank,

The problem is the nFlag parameter value you're passing. From VFP help: "Certain control events such as GotFocus, LostFocus, InteractiveChange, and ProgrammaticChange do not work if the second bit of the nFlags parameter is set, for example, nFlags set to 2". The ERROR method is not listed explicitly but above is applicable to it.

BINDEVENT(THIS,"Error",THIS.Errorist,"ErrorHandlerDevMode")
