HELP!!!! My Hotmail no longer works with Safari v. 5.0.6 and my Imac Leopard operating system 10.5.8. Please help me with any suggestions on what to do. Thank you. I cannot find any new downloads for Safari that work with Leopard. The newest ones only work with Lion. My Firefox browser still works though but I would rather use Safari and cannot access any e-mails or send any e-mails via Safari. This happened about 3 weeks ago and I thought it was just a glitch on Hotmail's site. Now I realize Hotmail must have released an update that no longer works with Leopard 10.5.8. PLEASE HELP ME!!!! Thanks to anyone and everyone who reads this and attempts to help me. I do not know what to do....
