The following program does not exit cleanly after pressing ‘Yes’ when  
asked  
‘Are you sure’?  
How do I free up the resources after exiting? You can use wxsugar  
(xrcise)  
to try out this mini program  
if you wish to create sample1.rb . Thank you.

It looks like you either need to make the confirmation dialog a child of  
the main frame of the whole program, or else call dialog.destroy  
explicitly when you’re finished with it, whatever the return value of  
show\_modal

def confirm\_closure  
# dlg = DIA\_Frame.new  
dlg = DIA\_Frame.new(the\_main\_window)  
if(dlg.show\_modal==Wx::ID\_YES) then  
dlg.end\_modal(Wx::ID\_YES)  
self.destroy  
end  
end
