Genero & fgl_window_current()

Hi!
	I would appreciate if someone could tell me how to replace the call to fgl_window_current() on Genero. "current window is " does not solve my problem since sometimes I need to call generic functions where I reaaly don't know wich was the original window. 

	let w_name = fgl_window_getoption('name')
 	( some code )
	call fgl_window_cuurent(w_name)

	TIA 
	Nuno
