Alessio,
Top level forms cannotr be modal (and for a single toplevel form you don't need it to be modal). However you can provide modality via read events. ie:

*main.prg
Local oForm
Do Form myForm Name oForm
oForm.Release
Release oForm
* code if any

*myForm.init
this.Show
Read events

*myForm some button click
thisform.hide()
clear events
