I tested the problem you pointed with setfocus...

1.in form.init if you write:

thisform.text1.setfocus && Assigns the focus to a control.
thisform.windowstate=2  && or set at design time

this works as well

2.but if you inverse

thisform.windowstate=2 && or set at design time
thisform.text1.setfocus

the form dont maximize and set the focus to the control !

3.better way is to set your focus in form.activate event.that works.

form.init
thisform.windowstate=2 && or set at design time

form.activate
thisform.text1.setfocus
