For many, many years, the Peoplesoft users know this (infamous) message on the login page when using, well, a non-supported OS by Peoplesoft.
I remember Duncan found a workaround to hide this message, find out more here. Already 4 years ago…
Maybe I’m out of date by using my old – but very well running – laptop on Windows XP Pro SP3, here it is within the image HCM92004 (Peopletools 8.53.xx) :
What a surprise with the last image HCM92008 (Peopletools 8.54.02), using the same browser and of course the same old laptop and OS, the message is just gone :
Nice, but probably time for an OS upgrade anyway !
Addendum (19-Sept-2014): if my test was done on Firefox 30.0, it’s worth to read PeopleTools Simplifies Internet Explorer Certifications
