webservice configuration

hi everyone, I have installed Aras 11 SP5 when I try to create a webservice configuration I get the following error message Event handler failed with message: TypeError: window.parent.frames.tearoff_menu is undefined [function onformpopulated$user$handler(e) { try { if (onformpopulated1(e) === false) return false; } catch (exp) { aras.AlertError(aras.getResource('', 'ui_methods_ex.event_handler_failed'), aras.getResource('', 'ui_methods_ex.event_handler_failure_msg', exp.description ? exp.description : (exp + ' [' +arguments.callee.toString()+ ']')), aras.getResource('','common.client_side_err')); return false; } }] Any idea ? thanks in advance!
