It has nothing to do with the 'shape' I already verified this with other forms that are working properly.
I also, set the 'KeyPreview' to .T. I even create a new form that has PageFrame and the the ENTER key is working properly.
Rick, I don't understand what you mean by "Since the Windows standard is to use Enter to "press" the default command button (i.e. Default property is .T.), I'd check to see if you have any so designated."
Thanks in advance.
