The documentation I see lists

push_security_alert_yes($wait)
push_confirm_button_ok($title, $wait)
push_button_yes($title, $wait)
push_confirm_button_cancle($title, $wait)
[download]

as methods for Win32::IEAutomation::WinClicker. Are you sure $clicker->push_button_save( "File Download", 1 ); is correct? All the previous versions of Win32::IEAutomation::WinClicker v0.1 show the same methods; no push_button_save anywhere.
