I have a form with two textboxes (Text1 & Text2) and two commandbuttons (Command1 & Command2). Set the tab order to the following: Command1, Text1, Command2, Text2. Set the enabled property for Text2 and Command2 to .F.. I have the following code in the Click event of Command1:
THISFORM.Text2.Enabled = .T.
THISFORM.Text1.Enabled = .F.
THISFORM.Command2.Enabled = .T.
THISFORM.Command1.Enabled = .F.
THISFORM.Text2.SetFocus()

When I run this form and press the Command1 button the focus jumps to the command2 button. However, when I step through the code in the trace window it seems to work ok.

Any ideas?
