You must be using an old version of a browser, Hotmail must have just recently switched to where you must use a newer browser. I recommend FireFox 3.0, since that is what I switched too when I started having the exact same problem you did a few days ago. Works fine now (when using FireFox 3) Hope this helps!
Please advise if anyone out there has a similar problem and knows any solutions for the fix.
I have two computer login accounts (one Administrative and one Standard user) on my Windows Vista laptop. The Standard login account is for my sister.
I already tried to uninstall my java and re-installed it with the latest version. I also tried to delete the Standard account and re-added the account. I still could not open up any messages in Hotmail...I had similar problems with Hotmail messages before with the Standard account and I deleted it and it worked fine. Now, this method is not working anymore...
The strange thing is if I use my Administrative account, I could open any Hotmail messages. Does anyone know how to fix this problem? I would greatly appreciate your help.
