Actually, in the close button of the form I have:

IF thisform.winsock1.object.state > 2
thisform.winsock1.object.close()
ENDIF

but I realize that the CLOSE() method does not run unless I do

IF thisform.winsock1.object.state > 2
thisform.winsock1.close()
ENDIF

I am doing all this but the form closing is still hanging the fox app.
