Hi Matt,

I'm not sure, it's the best way for testing, but then I have the mystery like this, I add wait windows with some messages, trying to determine, waht's going on. For instance, you may try wait window in GotFocus() event and in KeyPress(). Also there could be code in textbox.when expression, which returns .f. and prevents from editting. Or you set up this column to be readonly somehow.
I would try explicitly set readonly=.f. in text2.gotfocus(), e.g.
this.parent.readonly=.f.
this.parent.parent.readonly=.f.

just to be sure.

Of course, these are just my methods of 'struggle'. You may invent your own.
